 1.56  07-Jan-2025  andvar fix various typos in commments.
 1.55  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.

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.

 1.41  26-Jun-2018  msaitoh branches: 1.41.2;
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.
 1.40  22-Jun-2018  msaitoh It's not required to include net/bpfdesc.h. Remove it.
 1.39  07-Mar-2017  ozaki-r branches: 1.39.6; 1.39.12;
Apply deferred if_start (from maya@)

Fix PR kern/52023
 1.38  15-Dec-2016  ozaki-r branches: 1.38.2;
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
 1.37  10-Jun-2016  ozaki-r branches: 1.37.2;
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.
 1.36  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@:

 1.35  13-Apr-2015  riastradh Convert sys/dev to use <sys/rndsource.h>.
 1.34  10-Aug-2014  tls branches: 1.34.4;
Merge tls-earlyentropy branch into HEAD.
 1.33  02-Feb-2012  tls branches: 1.33.6; 1.33.20;
Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.
 1.32  13-Nov-2010  uebayasi branches: 1.32.8; 1.32.12;
Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.
 1.31  05-Apr-2010  joerg Push the bpf_ops usage back into bpf.h. Push the common ifp->if_bpf
check into the inline functions as well the fourth argument for
bpf_attach.
 1.30  19-Jan-2010  pooka branches: 1.30.2; 1.30.4;
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.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
 1.29  01-Dec-2009  dyoung Simplify the device activation routine.

 1.25  22-Sep-2009  tsutsui - replace shutdownhook_establish(9) with pmf_device_register1(9)

When adding/deleting multicast addresses, only whack the address
filter if the interface is marked RUNNING.

Fixes kern/27678.
 1.14  04-Jul-2004  chris Add the optional ability to parse the cs's eeprom data structure. I've made
it optional as I'm not able to confirm the eeprom format is the same on
earlier cs89x0's. Certainly the my 8920M and the data sheet for 8900A use the
same format.

This allows my RiscStation to examine the cs's eeprom to find it's mac
address, previously it was unable to do this, as the eeprom offsets were hard
coded for locating the mac address.
 1.13  10-Apr-2004  matt Don't set M_HASFCS. Rather than just print we got a bad packet length,

This is needed for some really screwball attachments of the CS8900.
 1.5  14-May-2002  augustss branches: 1.5.2;
ANSIfy.
 1.4  18-Apr-2002  thorpej * Fix the CS_IS_ENABLED() logic so that it actually evaluates to
"true" at the appropriate times for non-PCMCIA interfaces. This
means that the ENETRESET path in cs_ioctl() now runs, thus fixing
multicast (and IPv6) on my Shark. Yay.

* Simplify cs_hash_index(): Rather than taking the bottom 6 bits of
a big-endian CRC32 and reversing them, just take the top 6 bits of
a little-endian CRC32.

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
that had stubbed out code, other minor cleanups.
