 1.18  06-Oct-2023  msaitoh ixgbe: Rename some definitions, modify comment. No functional change.

Apply changes from FreeBSD's ix-3.3.31 and ixv-1.5.32.
- struct adapter *adapter -> struct ixgbe_softc *sc
- master -> primary
- black -> block
 1.17  24-Dec-2021  msaitoh branches: 1.17.4;
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.
 1.16  24-Dec-2021  msaitoh Change the first argument of ixgbe_send_vf_msg(). No functional change.

- This is a part of FreeBSD ix-3.2.17.
 1.15  24-Dec-2021  msaitoh Rename IXGBE_VT_MSGTYPE_{ACK,NACK} to IXGBE_VT_MSGTYPE_{SUCCESS,FAILURE}.

- Sync with FreeBSD ix-3.3.18.
- No functional change.
 1.14  10-Dec-2021  msaitoh Move PF mailbox initialization from ixgbe_attach() to ixgbe_init_iov().

From FreeBSD ix-3.3.18. No functional change.
 1.13  10-Dec-2021  msaitoh Change argument. No functional change. This file is not used in NetBSD.
 1.12  10-Dec-2021  msaitoh Remove unused argument. Note that this file is not used in NetBSD.
 1.11  30-Apr-2021  msaitoh Add missing __KERNEL_RCSID().
 1.10  30-Apr-2021  msaitoh Add NetBSD RCS IDs. No functional change.
 1.9  25-Jan-2021  mrg branches: 1.9.4;
s/boolean_t/bool/. boolean_t is obsolete (from Mach), and this
also fixes a new build issue in libkvm on sparc*.
 1.8  07-Sep-2020  msaitoh branches: 1.8.2;
- Remove extra callout_stop() in ixgbe_detach(). Found by knakahara@.
- Rename ix{gbe,v}_free_workqueue() to ix{gbe,v}_free_deferred_handlers().
- Add KASSERT() to functions who are called from ixgbe_handle_admin().
 1.7  25-Jun-2020  msaitoh Reduce ixgbe's busy loop using with workqueue and kpause.

- Use workqueue instead of softint to make some functions sleepable.
- Use new workqueue and enqueue it in ixgbe_local_timer() and
ixgbe_recovery_mode_timer() to make them sleepable.
- Make new ixgbe_delay() and use it. This functions sleeps if the time is
more than equals 1 tick. If it's not, do delay().
 1.6  27-Jun-2019  msaitoh branches: 1.6.2;
Sync with FreeBSD ix-3.3.8 part 1. No functional change in this part:
- Move ixgbe_toggle_txdctl() to ixgbe_common.c and modify a bit.
No functional change because this function is currently used for SR-IOV
and it's not used in NetBSD.
- Some modification to match the latest netmap API.
- Modify ixgbe_hic_unlocked(). No functional change because neither
IXGBE_HOST_INTERFACE_APPLY_UPDATE_CMD(0x38) nor
IXGBE_HOST_INTERFACE_SHADOW_RAM_READ_CMD(0x31) are used.
- Add ixgbe_clear_mbx(). No functional change because this function is not
used yet.
- Add some not-yet-used register definitions.
- Whitespace fixes.
 1.5  06-Dec-2018  msaitoh 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.
 1.4  03-Sep-2018  riastradh Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)
 1.3  04-Apr-2018  msaitoh branches: 1.3.2;
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.
 1.2  15-Mar-2018  msaitoh Add some changes from ix-3.2.17.tar.gz and r328265. Not fully synchronized.
Some others (e.g. sfp cage interrupt and bypass adapter stuff) will be merged
later:
- Initialize firmware command buffer correctly in ixgbe_read_ee_hostif_X550()
and ixgbe_read_ee_hostif_buffer_X550(). These functions are used when reading
NVM.
- Fix a bug that ixgbe_mng_present() misunderstand management capability on
X550 and newer on some environment. X550 changed FWSM bit definition.
See X540 document and X550's document and compare them.
- Fix checksum calculation in ixgbe_set_fw_drv_ver_generic(). This function is
not used in NetBSD.
- Add some unused funtions.
- Whitespace fix.
 1.1  30-Aug-2017  msaitoh branches: 1.1.2; 1.1.4; 1.1.6;
- 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.

- 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.

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.

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.

Read sc_if_flags after taking core lock. Same as if_wm.c rev. 1.418.

Add some changes from ix-3.2.17.tar.gz and r328265. Not fully synchronized.

Some others (e.g. sfp cage interrupt and bypass adapter stuff) will be merged
later:

- Initialize firmware command buffer correctly in ixgbe_read_ee_hostif_X550()
and ixgbe_read_ee_hostif_buffer_X550(). These functions are used when reading
NVM.
- Fix a bug that ixgbe_mng_present() misunderstand management capability on
X550 and newer on some environment. X550 changed FWSM bit definition.
See X540 document and X550's document and compare them.
- Fix checksum calculation in ixgbe_set_fw_drv_ver_generic(). This function is
not used in NetBSD.
- Add some unused funtions.
- Whitespace fix.
- Check offset correctly in ixgbe_get_oem_prod_version(). Note that this
function is not used.
- Set PHY correctly in ixgbe_setup_mac_link_sfp_x550a() if a device is a
C3000 KR SFP+.

Fix race about writing adapter->link_active for ixg(4).
adapter->link_active is updated by ixgbe_update_link_status() only.

The function is called from the following four functions.
- ixgbe_media_status()
- ixgbe_local_timer1()
- ixgbe_stop()
- ixgbe_handle_link()

The functions other than ixgbe_handle_link() call ixgbe_update_link_status()
with holding IXGBE_CORE_LOCK, however ixgbe_handle_link() calls it without
holding IXGBE_CORE_LOCK. That can cause race. So, add IXGBE_CORE_LOCK to
ixgbe_handle_link().

Tested by msaitoh@n.o and me.

Fix race about writing adapter->link_active for ixv(4).
adapter->link_active is updated by ixv_update_link_status() only.

The function is called from the following two functions.
- ixv_media_status()
- ixv_handle_link()

ixv_media_status() calls ixv_update_link_status() with holding
IXGBE_CORE_LOCK, however ixv_handle_link() calls it without
holding IXGBE_CORE_LOCK, the same as ixg(4).

ok by msaitoh@n.o.

- Add link related softint's counter.
- Fix indent.

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.

- 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.
