 1.41  04-Oct-2025  thorpej Add a shared function to query the common properties used for configuring
an Ethernet address.

s/mulicast/multicast/
s/muticast/multicast/
s/muliplicator/multiplicator/
s/muti-precision/multi-precision/
 1.39  25-Jun-2025  andvar s/collosion/collision/ in comment.
 1.38  01-Dec-2024  andvar s/availble/available/ in comment.
 1.37  07-Sep-2024  andvar spelling and grammar fixes, mainly in comments.
 1.36  07-Jul-2023  martin branches: 1.36.6;
Fix locking error when setting the multicast filter to accept all
multicast frames, pointed out by Lwazi Dube.
 1.35  25-Sep-2022  thorpej Remove unnecessary include of <sys/malloc.h>.
 1.34  18-Sep-2022  thorpej Eliminate use of IFF_OACTIVE.
 1.33  31-Dec-2021  riastradh sys: Use if_init wrapper function.

Exception: Not in kern_pmf.c, for the kind of silly reason that it
avoids having kern_pmf.c refer to symbols defined only in net; this
avoids a pain in the rump.
 1.32  05-Dec-2021  msaitoh s/receieve/receive/
 1.31  10-Nov-2021  msaitoh s/endianess/endianness/
 1.30  11-Sep-2021  andvar Add missing double p and d for stopped and overriden accordingly.
Fix few more typos along the way, mainly in copy-pasted comments.
 1.29  27-Jun-2020  jmcneill prop_data_data_nocopy -> prop_data_value
 1.28  02-Apr-2020  nisimura add aprint_debug_dev() call for CI20
 1.27  02-Apr-2020  skrll Fix evmips CI20 build
 1.26  31-Mar-2020  nisimura fix negated loop condition. make break when reset.
 1.25  31-Mar-2020  nisimura add comment to clearify hw nature
 1.24  31-Mar-2020  nisimura - reorgazine the entire structure to utilise ifmedia(4)/mii(4) and
redefine starting point of debug.
- nuke duplicated standard MII register definition. Davicom PHY extension
is defined in dev/mii/dmphyreg.h
 1.23  29-Mar-2020  nisimura reorganise rcv frame address filter code
 1.22  29-Jan-2020  thorpej Adopt <net/if_stats.h>.
 1.21  29-May-2019  msaitoh branches: 1.21.4;
Even if we don't use MII(4), use the common path of SIOC[GS]IFMEDIA in
sys/net/if_ethersubr.c if we can.
- Add ec_ifmedia into struct ethercom.
- ec_mii in struct ethercom is kept and used as it is. It might be used in
future. Note that some Ethernet drivers which _DOESN'T_ use mii(4) use
ec_mii for keeping the if_media. Those should be changed in future.
 1.20  28-May-2019  msaitoh Use ETHER_LOCK()/ETHER_UNLOCK() for all ethernet drivers to protect ec_multi*.
 1.19  23-May-2019  msaitoh Whitespace fix (mainly tabify).
 1.18  23-May-2019  msaitoh -No functional change:
- KNF
- u_int*_t -> uint*_t.
 1.17  24-Apr-2019  msaitoh KNF. No functional change.
 1.16  05-Feb-2019  msaitoh Remove very old IFF_NOTRAILERS flag.
 1.15  26-Jun-2018  msaitoh branches: 1.15.2;
Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same
as FreeBSD.

This change also fixes a bug that the direction is misunderstand on some
environment by passing the direction to bpf_mtap*() instead of checking
m->m_pkthdr.rcvif.
 1.14  22-Jun-2018  msaitoh Simplify like other drivers. NULL check of ifp->if_bpf is done in
bpf_mtap(), so it's not required to do it here.
 1.13  22-Jun-2018  msaitoh It's not required to include net/bpfdesc.h. Remove it.
 1.12  29-Jul-2017  riastradh branches: 1.12.2;
Check for MCLGET failure in dme_alloc_receive_buffer.

From Ilja Van Sprundel.
 1.11  15-Dec-2016  ozaki-r branches: 1.11.8;
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
 1.10  10-Jun-2016  ozaki-r branches: 1.10.2;
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.
 1.9  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@:
http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html

Acknowledgment: riastradh@ greatly helped this work.
Thank you very much!
