 1.32  06-Oct-2023  msaitoh ixgbe: Cleanup. No fucntional change.

Remove unused code, fix whitespace and modify comment to reduce against
FreeBSD(mainly from ix-3.3.35).
 1.31  06-Oct-2023  msaitoh ixg(4): Add 82599 LS once again.

- From:
FreeBSD: 9228ac3a69c4c7401a743e6465e118101a2beeb0
DPDK: 549ccd3dc01539e060597b503f2b65b272de3347
- This was removed 5 years ago. From the commit message:
> Remove IXGBE_DEV_ID_82599_LS(0x154f) support again. I don't know why. This
> was added in ix-3.2.18.tar.gz(NetBSD: ixgbe_82599.c rev. 1.20) and
> removed in ix-3.3.6.tar.gz.
 1.30  04-Oct-2023  msaitoh ixgbe: Fix typo in comment. No functional change.
 1.29  24-Dec-2021  msaitoh branches: 1.29.4;
Add code to support API version 1.5. No functional change.

- This change adds almost all code to support API 1.5 except real negotiation
and upgrade mailbox functions.
- From ix-3.3.18, ix-3.3.22 and ixv-1.5.24.
 1.28  24-Dec-2021  msaitoh Update copyright to 2020.

FreeBSD: 8455e365f77f5b66ac9521dbcd690f79345ce147
 1.27  14-Dec-2021  msaitoh Add IPv6 mask for flow director.

- FreeBSD: c4f73d5d6a6c0117e08a03920cce69202865ba13 or ix-3.3.18
DPDK: 21feefa2fcd5899ee26a10be405c17c0a1109860

Write FDIRIP6M register to allow flow director filter
to set ipv6 rules without setting ipv6 source/destination address.

- No functional change because NetBSD doesn't support flow director.
 1.26  10-Dec-2021  msaitoh Whitespace fix. Sync with FreeBSD ix-3.3.14.
 1.25  10-Dec-2021  msaitoh Remove unnecessary return value check.

DPDK: d8e52b2cf771c31b523b46852fd86225b5a2c721
 1.23  30-Apr-2021  msaitoh Add missing __KERNEL_RCSID().
 1.22  23-Dec-2019  msaitoh branches: 1.22.12;
Add recovery code for unsupported SFP+.

Before this commit:
If an unsuppored SFP module is inserted before booting, the driver attach
failed and there was no way to recover form it without rebooting or
detaching/reattaching drvier (drvctl -d && drvctl -r pciN).
After this commit:
We can automatically recover any time by replacing it with a supported
module.
 1.21  06-Dec-2018  msaitoh branches: 1.21.4;
Apply FreeBSD ix-3.3.6.tar.gz's change to NetBSD. Tested on C3000 and X550-T1,
but not tested on Xeon D:
- Add firmware recovery mode for X550, X550A(Xeon D) and X550EM (C3000):
- FreeBSD always set IXGBE_FEATURE_RECOVERY_MODE without checking the
NVM image version. We compare it against 2.0 to not to make new callout and
not to call extra atomic operations.
- In some FreeBSD's sysctl functions, atomic_load_acq_int() is called
before a null pointer check. We call it after null pointer check.
- Before calling atomic_load_acq_uint(), check adapter->feat_en flags
to save atomic operation call.
- We don't check recovery_mode in ixgbe_set_sysctl_value() because this
function doesn't touch any hardware register.
- NetBSD don't have FreeBSD's atomic_load_acq_int()-like function, so do it
with membar_sync(). Thanks riastradh@ for the advice.
- FreeBSD's ix-3.3.6 changed ixgbe_enable_aim from TRUE to FALSE, but we will
keep it as TRUE because we have already fixed some bugs.
- Remove IXGBE_DEV_ID_82599_LS(0x154f) support again. I don't know why. This
was added in ix-3.2.18.tar.gz(NetBSD: ixgbe_82599.c rev. 1.20) and removed in
ix-3.3.6.tar.gz.
- On X550EMU, use ixgbe_identify_sfp_module_X550em() instead of
ixgbe_identify_module_generic(). ixgbe_identify_sfp_module_X550em() has
extra check (e.g. exclude 1G copper).
- if_sriov.c's change doesn't affect to NetBSD because we don't support
SR-IOV PF function.
 1.20  11-Jun-2018  msaitoh branches: 1.20.2;
Apply changes of FreeBSD ix-3.2.18.tgz:
- Add IXGBE_DEV_ID_82599_LS(0x154f) support.
- Increase timeout for newer than ixgbe_mac_X550 (i.e. Xeon-D and Denverton)
in ixgbe_acquire_swfw_sync_X540().
- Add some unused macros (IXGBE_FW_LESM_*).
 1.19  04-Apr-2018  msaitoh Sync with FreeBSD r331224 except ixv_if_update_admin_status()'s change:
- Fix length of reading buffer when the command is Read Flash in
ixgbe_host_interface_command().
- Add missing start_hw() call in ixv_init_locked(). This is not a real bug
because start_hw just set hw->adapter_stopped to false and anyone refer it.
- Style change.
- Update comment.
 1.18  04-Apr-2018  msaitoh Sync with the remaining part of FreeBSD r328265 except sfp_reinit stuff:
- Always schedule module intterrupt in ixgbe_config_link() when a device is
SFP+ based.
- Use not loop index but txr->me in ixv_initialize_{transmit,receive}_units().
It's required for VMDQ but NetBSD doesn't use it, so it's not a bug in
NetBSD.
- Simplify ixgbe_bp_wd_set(). No functional change.
- Whitespace.
 1.17  30-Mar-2018  msaitoh - Add missing IFM_NONE support. If a interface support linkdown,
"ifconfig ixgN media none" drpos link. Not all interface can do link down.

Tested:
82598 AT2 (T)
92599 SF+(SFI) (X520-DA2)
X540
X550-T1
X550EM_x (X10SDV-8C-TLN4F)
X550EM_a (A2SDi-H-TP4F port 0, 1 (T))

Doesn't work:
X550EM_a (A2SDi-H-TP4F port 2, 3 (SFP+ (KR)))
X550EM_a (MA10-ST0 port 2, 3 (SFP+ (SFI)))
(Denverton SFP+ can't force link down because SFP+'s TX_DISABLE pin is
pull down. Is there a way to shutdown SFP+ cage's power?)
Not tested:
82598 fiber.

- Change some functions static.
 1.16  06-Dec-2017  msaitoh branches: 1.16.2;
Sync with FreeBSD's r326022. All of the following changes have no influence
to netbsd:
- Check ETHERCAP_VLAN_HWTAGGING in ixgbe_setup_vlan_hw_support(). This change
has no influence to netbsd because it's enabled by default and NetBSD has
no API to disable it.
- Fix for netmap module.
- Remove never defined UDP_IPV4_EX
- Add SPDX-License-Identifier
 1.15  30-Aug-2017  msaitoh - Sync with FreeBSD r320688 (and up to r322865):
- Add C3000(Denvertion(-NS)) support.
- Add bypass function support for bypass adapters. Sysctls are provided.
Not tested because I have no any bypass adapter.
- ixv(4): set RSS mapping.
- Change EEE sysctl.
- ixv(4): Add TSOv6.
- ixv(4): Mailbox API 1.2 and more are implemented and comment says it
negotiate with 1.2 but it really does 1.1...
- Remove thermal test sysctl.
- Fix unknown bugs.
- Print driver feature capabilities and enable bits when verbose boot.
 1.14  02-Dec-2016  msaitoh branches: 1.14.8;

- Fix ixgbe_set_advertise() a bit. At least, FreeBSD r294578 is required
to work hw.ixg0.advertise_speed sysctl correctly.
 1.12  01-Dec-2016  msaitoh Update ixg(4) and ixv(4) up to FreeBSD r280197:
- Add support for 82599_QSFP_SF_QP and X540T1.
- Add partial support for X55x. It's required to sync with FreeBSD r282299
to support X55x.
- Bugfixes.
 1.11  13-Aug-2015  msaitoh branches: 1.11.2;

sys/dev/pci/ixgbe/ixv.c 1.3-1.4
sys/dev/pci/ixgbe/ixv.h 1.3

- Sync ixg(4) up to FreeBSD r230572.
- Fix in the interrupt handler to make sure the stack TX queue is processed.
(FreeBSD r222588)
- The maximum read size of incoming packets is done in 1024-byte increments.
The current code was rounding down the maximum frame size instead of
routing up, resulting in a read size of 1024 bytes, in the non-jumbo
frame case, and splitting the packets across multiple mbufs.
(FreeBSD r225045)
- Consequently the above problem exposed another issue, which is when
packets were splitted across multiple mbufs, and all of the mbufs in the
chain have the M_PKTHDR flag set. (FreeBSD r225045)
- Use the correct constant for conversion between interrupt rate
and EITR values (the previous values were off by a factor of 2)
(FreeBSD r230572)
- Make dev.ix.N.queueM.interrupt_rate a RW sysctl variable. Changing
individual values affects the queue immediately, and propagates to all
interfaces at the next reinit. (FreeBSD r230572)
- Add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual interrupt
counts. (FreeBSD r230572)
- Some netmap related changes.
- Fix a bug that vlan setting may not apply to the parent interface correctly.
- Add 82599EN_SFP and 82599_SFP_SF_QP.
- Modify to make Intel Intel 10G Ethernet (ixg(4)) virtual function ixv(4)
compilable. Not completed yet. It's required to use MSI-X.
- Change comments, tabs and spaces to make difference among *BSDs small.
- Enclose macro argument correctly. Same as *BSDs. No binary change.
- Add missing parenthesis in IXGBE_CORE_LOCK_ASSERT() macro. No binary change.

- Use MCLGET() instead of homegrown cluster (jcl) allocation mechanism.
Before this commit, resource shortage was easily occurred because
the total number of the clusters is small.
- Improve performance:
- Use m_adj(ETHER_ALIGN) more.
- Sprinkle __predict_false() in the RX path.
- Don't pre-allocate a cluster for RXCOPY case to improve short
packet's performance.
- Call bus_dmamap_unload(9) via ixgbe_dmamap_unload(), before freeing
DMA buffer. Also, when the buffer is already freed, do not call
bus_dmamap_unload(9) (no resource leaks with this change). This
change is required to make ixg(4) work on alpha.
- Keep m_len and m_pkthdr.len consistent to prevent panic on arm.
- Fix panic when bus_dmamap_load_mbuf() failed in
ixgbe_setup_receive_ring().
- Added BUS_DMA_COHERENT flag to bus_dmamem_map() to improve stability
on aarch64.
- Use uint64_t instead of bus_addr_t for the TX descriptor's buffer
address. At least, this change is required for macppc
(sizeof(bus_addr_t) == 4) to make TX work.
- Fix little-endian dependence.
- Set rxr->next_to_refresh correctly in ixgbe_setup_receive_ring().
- Refresh unrefreshed descriptors' buffers correctly.
- Don't call bus_dmamap_sync with rx_mbuf_sz(== MCLBYTES) to prevent
panic.
- Save the discard_multidesc state to not to forget the state by
exiting rxeof().
- Add missing increment of no_mbuf error counter.
- Don't increment no_mbuf evcnt(9) when discarding multi-descriptor
packet.
- ixv: Modify error message to sync with ixgbe.c
- Print the error value of ixgbe_reset_hw() for debugging.
- Remove extra unlock/lock processing around if_percpuq_enqueue().
- Refactor rxr->next_to_check updating.
- Add new sysctl "rx_copy_len".
- Add a new sysctl to read rxr->next_to_refresh.
- Print error number when error occurred.
- Rename ix{gbe,v}_stop() with ix{gbe,v}_stop_locked(). No functional
change.
- Don't use fixed value.
- Comment out flow director processing in fast path.
- Add missing NetBSD RCS IDs and __KERNEL_RCSID()s.
- KNF.
- Fix typos.

Add recovery code for unsupported SFP+.

Before this commit:
If an unsupported SFP module is inserted before booting, the driver attach
failed and there was no way to recover form it without rebooting or
detaching/reattaching driver (drvctl -d && drvctl -r pciN).

After this commit:
We can automatically recover any time by replacing it with a supported
module.

Sync ixgbe up to 20190717 except ETHERCAP or ixv's VLAN stuff:
- Add firmware recovery mode for X550, X550A(Xeon D) and X550EM(C3000).
- Remove IXGBE_DEV_ID_82599_LS(0x154f) support again.
- On X550EMU, use ixgbe_identify_sfp_module_X550em() instead of
ixgbe_identify_module_generic(). ixgbe_identify_sfp_module_X550em()
has extra check (e.g. exclude 1G copper).
- It's not required to calculate unused queues' statistics.
- Remove ETHERCAP_VLAN_HWFILTER's definition.
- Match 82598_BX(0x1508), 82599_KR(0x1517), 82599_SFP_EM(0x1507),
X550EM_X_XFI(0x15b0), X550EM_A_QSFP(0x15ca) and
X550EM_A_QSFP_N(0x15cc)
- Add missing XFI support into ixgbe_get_link_capabilities_X550em().
- Other than IXGBE_VF_RESET should wait ACK, so use
ixgbevf_write_msg_read_ack() instead of write_posted() in
ixgbe_update_mc_addr_list_vf().
- When ixv_check_link() failed in the watchdog function, reset the
interface.
- Remove RXCSUM register modification in
ixv_initialize_receive_units(). It seems it's not required.
- Remove some debug printf in ixv_print_debug_info().
- Calculate vector's bit location correctly when the vector >= 31
in ixgbe_allocate_msix().
- Fix hung queue check when the queue number >= 31.
- On ENETRESET case, not continue and quit the ifflags_cb() function
because if_init() will do the same thing.
- Fix bugs in unused code.
- Fix typo in comment.
- Fix typo in unused code.
- Whitespace fixes. KNF.

Apply changes of FreeBSD ix-3.2.18.tgz:
- Add IXGBE_DEV_ID_82599_LS(0x154f) support.
- Increase timeout for newer than ixgbe_mac_X550 (i.e. Xeon-D and Denverton)
in ixgbe_acquire_swfw_sync_X540().
- Add some unused macros (IXGBE_FW_LESM_*).
--
Remove nmbclusters check. We don't use the mbuf cluster. The old code also had
a bug that ixgbe_total_ports adds two every port and never decrement in
the detach path. Found by hikaru@.
The code was removed in FreeBSD when it switched to use iflib and OpenBSD
removed the code 8 years ago.

Sync with the remaining part of FreeBSD r328265 except sfp_reinit stuff:
- Always schedule module intterrupt in ixgbe_config_link() when a device is
SFP+ based.
- Use not loop index but txr->me in ixv_initialize_{transmit,receive}_units().
It's required for VMDQ but NetBSD doesn't use it, so it's not a bug in
NetBSD.
- Simplify ixgbe_bp_wd_set(). No functional change.
- Whitespace.

Sync with FreeBSD r331224 except ixv_if_update_admin_status()'s change:
- Fix length of reading buffer when the command is Read Flash in
ixgbe_host_interface_command().
- Add missing start_hw() call in ixv_init_locked(). This is not a real bug
because start_hw just set hw->adapter_stopped to false and anyone refer it.
- Style change.
- Update comment.

Fix the problem between eitr and link_speed.

In ixgbe_msix_que(), que->eitr_setting is limited to IXGBE_MIN_RSC_EITR_10G1G
when link_speed is 1Gbps or 10Gbps. However, que->eitr_setting is set to EITR
register in the *next* Tx/Rx interrupt. If link_speed changes from 100Mbps to
1Gbps ro 10Gbps, que->eitr_setting which is not limited can be set to EITR
register, that is, the problem fixed by ixgbe.c:r1.124 can occur in this case.

To fix this case, que->eitr_setting should be clear when link_speed is changed
or link state is changed.

Furthermore, expand the variants used for AIM (txr->bytes, txr->packets,
rxr->bytes and rxr->packets) from u32 to u64 to avoid wraparound which causes
que->eitr_setting calculation mistake.
XXX pullup-8

Don't write EIMC directly. It is required to manage with struct ix_queue status.
XXX pullup-8

- Add missing IFM_NONE support. If a interface support linkdown,
"ifconfig ixgN media none" drpos link. Not all interface can do link down.
Tested:
82598 AT2 (T)
92599 SF+(SFI) (X520-DA2)
X540
X550-T1
X550EM_x (X10SDV-8C-TLN4F)
X550EM_a (A2SDi-H-TP4F port 0, 1 (T))
Doesn't work:
X550EM_a (A2SDi-H-TP4F port 2, 3 (SFP+ (KR)))
X550EM_a (MA10-ST0 port 2, 3 (SFP+ (SFI)))
(Denverton SFP+ can't force link down because SFP+'s TX_DISABLE pin is
pull down. Is there a way to shutdown SFP+ cage's power?)
Not tested:
82598 fiber.
- Change some functions static.

Avoid issues caused by sending old packets at next link-up time.

This modification consists by the following two parts.
- drain packets in if_snd queue or corresponding txr->txr_interq
when link_active == false in ifp->if_start(), ifp->if_transmit(),
and deferred Tx processing
- drain packets in if_snd queue and all of txr->txr_interq's
at link-down time
ok by msaitoh@n.o.

Fix long standing bug that 82598 SFP+ panics in ixgbe_handle_mod() because
hw->mac.ops.setup_sfp is NULL. This change is a part of FreeBSD r327031.

Fix a bug that "ifconfig ixgN down up" forgot IFM_NONE setting.
- Don't assume autoneg == 0 is the first call of ixgbe_config_link().
Check ifm_media, too.
- Don't override autoneg_advertised in ixgbe_get_phy_id_fw() to not to
be inconsistent with if_media value.

Sync with FreeBSD's up to r326022, fix bugs and some improvements:
- Don't limit number of queue pair to 8. Take chip's max TX queues and
max RX queues into account.
- Add C3000 (Denverton) support.
- Add bypass function support for bypass adapters.
- Change EEE sysctl.
- Remove thermal test sysctl.
- ixv(4): set RSS mapping.
- ixv(4): Add TSOv6.
- ixv(4): Fix hardware counter.
- ixv(4): Make TX/RX descriptors size the same as ixg(4).
- ixv(4): Print device name in ixv_attach().
- ixv(4): Make mailbox statistic counters evcnt(9).
- ixv(4): Fix a problem that mailbox interrupt never occurred.
- ixv(4): Don't check neither VTEICR nor VTEICS same as Linux. It
seems that both registers can't be used to check which MSI-X vector
is triggered.
- ixv(4): Print Mailbox API version.
- Print driver feature capabilities and enable bits when verbose boot.
- Fix a bug that X550EM_A (Denverton) can't force 10BaseT.
- Remove all half-duplex setting because of the chip specification.
- Add 2.5GBASE-T and 5GBASE-T support.
- Set ifm_baudrate correctly.
- Protect ec_multi* with mutex like other MP safe Ethernet drivers.
- On X550 and newer, print NVM Image Version with %u.%02x.
- On X540, print PHY FW Revision with %u.%x. 0x4030 will be printed
as "Revision 4.3 ID 0x0"
- Fix value check of OEM_NVM_IMAGE_VER.
- Print PHY ID only for copper PHY.
- Fix a bug that X550 and newer didn't linkup if it forces
100BaseTX-FDX or 10BaseT-FDX.
- Fix a bug that RX may accesses freed area. It also fixes a problem
that if_init() takes long time on many core machine.
- Check ETHERCAP_VLAN_HWTAGGING in ixgbe_setup_vlan_hw_support(). This
change has no influence to netbsd because it's enabled by default
and NetBSD has no API to disable it.
- Whitespace fix.

ixgbe: Reorder some event counters for readability.

ixg(4): Rename some descriptions of event counters.
- Rename some descriptions from register name to the meaning.
- For the same meaning's counters, add "(soft)" or "(reg)".
The former is for a software level counter and the latter is for a
statistics counter register based.

ixg(4): Count Queue Bytes {Transmit, Receive} counter.

ixg(4): Reorder some flow control related event counters for readability.

ixg(4): Rename some descriptions of flow control related event conters.
Remove obsolete comment.

ixgbe: Fix typo in comment. No functional change.

ixv(4): Improve error check.
ixgbe_vf.c rev. 1.31 changed the behavior of the ixgbe_check_mac_link_vf()
function. It was from FreeBSD's ixv-1.5.25 to resolve mailbox collision
problem. The change had a problem that error checks have not done at all if
the API version >= 1.5. Fix it. From FreeBSD ixv-1.5.27.

ixv(4): Add new IXGBE_VF_GET_LINK_STATE message support.
PF can control vf's link state by this change. Note that Linux's PF driver
can't control the link to force up (i.e. ip link set XXX vf Y state enable).
From FreeBSD ixv-1.5.30.

ixg(4): Update FCTRL after writing multicast filter. Same as other OSes.
From FreeBSD 395cc55d896654b8f75071e71e856b22aed87da5.

- Use MCLGET() instead of homegrown cluster (jcl) allocation mechanism.
Before this commit, resource shortage was easily occurred because
the total number of the clusters is small.
- Improve performance:
- Use m_adj(ETHER_ALIGN) more.
- Sprinkle __predict_false() in the RX path.
- Don't pre-allocate a cluster for RXCOPY case to improve short
packet's performance.
- Call bus_dmamap_unload(9) via ixgbe_dmamap_unload(), before freeing
DMA buffer. Also, when the buffer is already freed, do not call
bus_dmamap_unload(9) (no resource leaks with this change). This
change is required to make ixg(4) work on alpha.
- Keep m_len and m_pkthdr.len consistent to prevent panic on arm.
- Fix panic when bus_dmamap_load_mbuf() failed in
ixgbe_setup_receive_ring().
- Added BUS_DMA_COHERENT flag to bus_dmamem_map() to improve stability
on aarch64.
- Use uint64_t instead of bus_addr_t for the TX descriptor's buffer
address. At least, this change is required for macppc
(sizeof(bus_addr_t) == 4) to make TX work.
- Fix little-endian dependence.
- Set rxr->next_to_refresh correctly in ixgbe_setup_receive_ring().
- Refresh unrefreshed descriptors' buffers correctly.
- Don't call bus_dmamap_sync with rx_mbuf_sz(== MCLBYTES) to prevent
panic.
- Save the discard_multidesc state to not to forget the state by
exiting rxeof().
- Add missing increment of no_mbuf error counter.
- Don't increment no_mbuf evcnt(9) when discarding multi-descriptor
packet.
- ixv: Modify error message to sync with ixgbe.c
- Print the error value of ixgbe_reset_hw() for debugging.
- Remove extra unlock/lock processing around if_percpuq_enqueue().
- Refactor rxr->next_to_check updating.
- Add new sysctl "rx_copy_len".
- Add a new sysctl to read rxr->next_to_refresh.
- Print error number when error occurred.
- Rename ix{gbe,v}_stop() with ix{gbe,v}_stop_locked(). No functional
change.
- Don't use fixed value.
- Comment out flow director processing in fast path.
- Add missing NetBSD RCS IDs and __KERNEL_RCSID()s.
- KNF.
- Fix typos.

Add recovery code for unsupported SFP+.

Before this commit:
If an unsupported SFP module is inserted before booting, the driver attach
failed and there was no way to recover form it without rebooting or
detaching/reattaching driver (drvctl -d && drvctl -r pciN).

After this commit:
We can automatically recover any time by replacing it with a supported
module.

ixg(4): Remove unused and old function. No functional change.
- From FreeBSD's ix-3.3.32.

ixg(4): Add 82599 LS once again.
- From:
FreeBSD: 9228ac3a69c4c7401a743e6465e118101a2beeb0
DPDK: 549ccd3dc01539e060597b503f2b65b272de3347
- This was removed 5 years ago. From the commit message:
> Remove IXGBE_DEV_ID_82599_LS(0x154f) support again. I don't know why. This
> was added in ix-3.2.18.tar.gz(NetBSD: ixgbe_82599.c rev. 1.20) and
> removed in ix-3.3.6.tar.gz.

ixg(4): Filter out spurious link up indication
- Extend SFP+ cage crosstalk fix by re-checking link state after 5ms delay
to filter out spurious link up indication by transceiver with no fiber
cable connected.
- From FreeBSD:
In-tree: 04a5e6d7cadd06b10169c3c3a560649e7dc7444c
Out of tree: ix-3.3.33.

ixgbe: Simplify definitions. No functional change.
Both DEFAULT_{TX,RX}D and PERFORM_{TX,RX}D are 2048. Use DEFAULT_{TX,RX}D.
Same as FreeBSD.

ixgbe: Modify error message of wrong TX/RX descriptor size.
- Based from FreeBSD ix-3.3.35. I think ix-3.3.35's RING_INCREMENT(== 32)
is wrong. It should be 8(DBA_ALIGN / sizeof(union ixgbe_adv_[tr]x_desc)).
Linux also uses 8.

ixgbe: Remove NO_82599_SUPPORT and NO_X540_SUPPORT support. NFCI.
From FreeBSD ix-3.3.35. Note that this file is not used in NetBSD.

ixgbe: Enable interrupt after setting IFF_RUNNING. Same as FreeBSD x-3.3.35.

ixgbe: Cleanup. No fucntional change.

Remove unused code, fix whitespace and modify comment to reduce against
FreeBSD(mainly from ix-3.3.35).

ixgbe: Reorder some event counters for readability.

ixg(4): Rename some descriptions of event counters.
- Rename some descriptions from register name to the meaning.
- For the same meaning's counters, add "(soft)" or "(reg)".
The former is for a software level counter and the latter is for a
statistics counter register based.

ixg(4): Count Queue Bytes {Transmit, Receive} counter.

ixg(4): Reorder some flow control related event counters for readability.

ixg(4): Rename some descriptions of flow control related event conters.
Remove obsolete comment.

ixgbe: Fix typo in comment. No functional change.

ixv(4): Improve error check.
ixgbe_vf.c rev. 1.31 changed the behavior of the ixgbe_check_mac_link_vf()
function. It was from FreeBSD's ixv-1.5.25 to resolve mailbox collision
problem. The change had a problem that error checks have not done at all if
the API version >= 1.5. Fix it. From FreeBSD ixv-1.5.27.

ixv(4): Add new IXGBE_VF_GET_LINK_STATE message support.
PF can control vf's link state by this change. Note that Linux's PF driver
can't control the link to force up (i.e. ip link set XXX vf Y state enable).
From FreeBSD ixv-1.5.30.

ixg(4): Update FCTRL after writing multicast filter. Same as other OSes.
From FreeBSD 395cc55d896654b8f75071e71e856b22aed87da5.
