 1.93  05-Jul-2024  rin sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c

Compile-tested on amd64/ALL.

Suggested by knakahara@
 1.92  29-Jun-2024  riastradh if_stats(9): Add ifp argument to if_stat..._ref.

This will enable us to pass the ifp through to a dtrace probe inside.

No functional change intended in this change, but this is an API
change visible to modules so it shouldn't be pulled up.

- Simplify MII structure initialization and reference.

- KNF
 1.67  22-Jan-2019  msaitoh Change MII PHY read/write API from:

int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:

int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same

This change also fixes a bug that the direction is misunderstand on some

XXX need pullup to -8 branch
 1.62  15-Dec-2016  ozaki-r branches: 1.62.8;
Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input

The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
- Where/When if_ipackets is counted up
- Note that some drivers still update packet statistics in their own
way (periodical update)
- Moved bpf_mtap run in softint
- This makes it easy to MP-ify bpf

Proposed on tech-kern and tech-net
 1.61  08-Dec-2016  ozaki-r Apply deferred if_start framework

if_schedule_deferred_start checks if the if_snd queue contains packets,
so drivers don't need to check it by themselves.

KNF. Remove extra spaces. No functional change.
 1.59  10-Jun-2016  ozaki-r Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.
 1.58  09-Feb-2016  ozaki-r Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Additional information including performance numbers can be found
in the thread at tech-kern@ and tech-net@:

Fix mii_statchg to take a 'struct ifnet *' instead of device_t. This fixes

Some drivers converted to CFATTACL_DECL_NEW.
 1.54  30-Jan-2012  drochner Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive}
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.

Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

 1.42  11-Mar-2008  dyoung Prepare for PMF self-suspension: in the if_stop() methods, clear
IFF_UP and IFF_RUNNING before running the 'disable' step, instead
of after. Soon I will handle the 'disable' step by calling into
PMF, which may call if_stop(, 0). Ordinarily, that is harmless.
This change lets the if_stop() routines exit early when they find
on entry that IFF_RUNNING is not set.
 1.41  07-Feb-2008  dyoung branches: 1.41.2; 1.41.6;
Start patching up the kernel so that a network driver always has
the opportunity to handle an ioctl before generic ifioctl handling
occurs. This will ease extending the kernel and sharing of code
between drivers.

First steps: Make the signature of ifioctl_common() match struct
ifinet->if_ioctl. Convert SIOCSIFCAP and SIOCSIFMTU to the new
ifioctl() regime, throughout the kernel.
 1.40  19-Jan-2008  dyoung Make many ethernet drivers share the common code for MII media
handling, ether_mediastatus() and ether_mediachange(). Check for
a non-ENXIO error return from mii_mediachg(). (ENXIO indicates
that a PHY is suspended.)

This patch shrinks the source code size by 979 lines. There was
a 5100-byte savings on the NetBSD/i386 kernel configuration, ALL.

I have made a few miscellaneous changes, too:

gem(4): use LIST_EMPTY(), LIST_FOREACH().
mtd(4): handle media ioctls, for a change!
axe(4): do not track link status in sc->axe_link any longer
nfe(4), aue(4), axe(4), udav(4), url(4): do not reset all PHYs
on a change of media

Except for the change to mtd(4), no functional changes are intended.

 1.24.2.2  05-Jul-2005  tron Pull up revision 1.28 (requested by bouyer in ticket #548):
Write the station address using 8-bits writes instead of 16-bits.
This is what the linux driver does, and makes the DGE-550T work without the
STGE_CU_BUG hack. So remove the STGE_CU_BUG hack.
Set bit 0x0020 in STGE_DebugCtrl too, the linux driver does it (the comments
note this as a workaround, without more details. This doesn't seem to make
things worse).
Also initialize STGE_RxDMABurstThresh and STGE_RxDMAUrgentThresh, using
values from the linux driver.
Approved by Jason Thorpe.

VLAN ID uses pkthdr instead of mtag now. Contributed by s-yamaguchi@IIJ.
I just commit by proxy. Reviewed by joerg@n.o and christos@n.o, thanks.
See http://mail-index.netbsd.org/tech-net/2017/09/26/msg006459.html
--
only get vtag when we have vtag like the other drivers.
--
- only get the vtag if we have it like the other drivers
- mask the hardware vlan tag
--
- add a constant for the vlan mask.
- enforce that we have a tag before we get it.

Add support IC Plus IP1000* PHYs. PR/kern 42314 first reported by

Tomokazu HARADA and patch provided by Andrius V.

New sentence, new line.
Fix date. Add RCS Id.

KNF. No functional change.

STGE_PhyCtrl is not PHY register but MAC register, so use ukphy_status()
for IP1000A device.

- Use auto-negotiation when forcing 1000BASE-T.
- Add XXX comment for strange pause setting code. I suspect this is wrong.
- On my environments, 1000BASE-T half duplex doesn't work, so we might remove
IFM_1000T_HDX from this device in future.
- Define IPGPHY_SCR's address.
- Whitespace fix.

Add missing NetBSD RCS Id. Reported by Andrius V.
