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

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.

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.

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

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.

in the thread at tech-kern@ and tech-net@:

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.

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.

| 19-Feb-2007 |
rumble | Support the sq(4) interface on the Challenge S's IOPLUS mezzanine. This
requires us to configure the IOPLUS to use the appropriate DMA channel,
depending on what other expansion cards may be installed. Further, we need
to do a bit more configuration of the sq(4) DMA engine, which apparently
was formerly being configured properly by the PROM. Use the same values,
which appear to work fine.
Also, extend the gio_arb_config interface as needed.
NB: We're currently setting the IOPLUS board to long burst, but it may be
better to use realtime. This will require some experimentation.

rumble | Do not report unexpected interrupts when not debugging. These

rumble | Remove a few HPC1 register definitions for ones that don't exist.
Also, HPC1_ENET_INTDELAYVAL isn't a magic number. It turns the

rumble | Wrap seeq and hpc register reads and writes in macros for

|
| 1.23 |
| 29-Dec-2004 |
rumble | Fix the HPC1 transmit logic, which was previously very broken.
HPC1 does not mark transmitted descriptors like HPC3. We must
query the HPC1 chip to determine what it expects the next
descriptor to be, reclaim used ones, and restart if necessary. Each
revision's corresponding logic now lives in its own
sq_txring_hpc{1,3} function.
HPC1's transmit interrupt conditions also differ from HPC3, so
remove the INTR bits from descriptors when tagging new packets on
to the end of the chain in order to avoid unwanted interrupts.
Also, be extra careful when restarting the transmit ring. Since
transmit interrupts seem to be relatively slow on HPC1, sq_start
may be called while the DMA engine is quiescent, and before a
transmit interrupt is asserted. We cannot behave like HPC3, which
begins transmission from the first packet pulled from IFQ if the
DMA engine is quiescent as this would skip enqueued packets. It
appears that sq_start is never called before HPC3 asserts an
interrupt, which restarts the transmit queue at the appropriate
place. However, this often happens with HPC1 and we cannot assume
that if DMA is inactive in sq_start, then all previously queued
packets have fled the coop.
XXX Is there a similar race possible with HPC3?
HPC3 logic should remain functionally unchanged, and HPC1 should
finally work properly.
