 1.36  05-Nov-2023  andvar Use DPRINTF instead of __gsfb_print() to print smap status.

__gsfb_printf() is defined only with the GSFB_DEBUG_MONITOR option.
 1.35  18-Sep-2022  thorpej Eliminate use of IFF_OACTIVE.
 1.34  11-Feb-2022  riastradh playstation2: Somewhat belated device_t/softc split.
 1.33  21-Nov-2020  thorpej malloc(9) -> kmem(9)

XXX Audit use of KM_NOSLEEP here.
 1.32  29-Jan-2020  thorpej branches: 1.32.6;
Adopt <net/if_stats.h>.
 1.31  10-Nov-2019  chs branches: 1.31.2;
in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.
 1.30  29-May-2019  msaitoh KNF. No functional change.
 1.29  29-May-2019  msaitoh Whitespace fix. No functional change.
 1.28  05-Feb-2019  msaitoh Remove very old IFF_NOTRAILERS flag.
 1.27  26-Jun-2018  msaitoh branches: 1.27.2;
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.
 1.26  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.
 1.25  22-Jun-2018  msaitoh It's not required to include net/bpfdesc.h. Remove it.
 1.24  08-Feb-2018  dholland branches: 1.24.2;
Typos.
 1.23  15-Dec-2016  ozaki-r branches: 1.23.8;
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
 1.22  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.
 1.21  10-Jun-2016  ozaki-r branches: 1.21.2;
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.
 1.20  03-Apr-2016  martin Fix bpf_mtap argument
 1.19  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@:

Acknowledgment: riastradh@ greatly helped this work.
Thank you very much!
 1.18  13-Apr-2015  riastradh MD rnd.h cleanups. Please let me know if I broke anything!
 1.17  10-Aug-2014  tls branches: 1.17.4; 1.17.6;
Merge tls-earlyentropy branch into HEAD.
 1.16  29-Jun-2014  mrg NBPFILTER is no more.
 1.15  31-Mar-2014  martin branches: 1.15.2;
Bring back the playstation2 port - now that a toolchain for it is
available again.
 1.14  05-Dec-2009  pooka branches: 1.14.10; 1.14.16;
Remove support for NetBSD/playstation2.
 1.13  28-Apr-2008  martin branches: 1.13.14;
Remove clause 3 and 4 from TNF licenses
 1.12  12-Mar-2008  dyoung branches: 1.12.2; 1.12.4;
In smap_stop(), clear IFF_RUNNING before disabling the device.
 1.11  19-Jan-2008  dyoung branches: 1.11.2; 1.11.6;
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.

XXX This patch affects more architectures than I can feasibly
XXX compile and run. I have compiled macppc, sparc64, i386. I
XXX have run the patches on i386 boxen with bnx(4) and sip(4).
XXX Compiling and running on evbmips (MERAKI, ADM5120) is in
XXX progress.

 1.15.2.2  10-Aug-2014  tls Rebase.
 1.15.2.1  07-Apr-2014  tls Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

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.
