It's not required to include net/bpfdesc.h. Remove it.
--
Simplify like other drivers. NULL check of ifp->if_bpf is done in
bpf_mtap(), so it's not required to do it here.

Remove duplicated inclusion of net/bpf.h.

Remove duplicated inclusion of net/bpf.h.

Simplify bpf_mtap() call. No functional change.

 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

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!

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.

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.

Hi Perry!

White space nits.

Pull up revision 1.5 (requested by thorpej in ticket #942):
  In qtinit(), don't skip initialization if the interface is
  already RUNNING.  ether_ioctl() will call (*if_init)() when
  flags change.  Instead, do what other drivers do, and stop
  the interface in this case before re-initializing.
  In qtioctl(), now that qtinit() does the right thing, remove
  the check for the IFF_PROMISC change.
  When adding or deleting multicast addresses, only change
  the address filter if the interface is marked RUNNING.
  Fixes PR#37678.

file if_qt.c was added on branch ktrace-lwp on 2004-08-03 10:50:28 +0000

Add stop routine. Add support for turning the device into promiscous mode.
Force interrupt in probe so that the interrupt vector can be detected.

bus-ify. Make bpf work, but no promiscuous mode yet.

Make the qt driver work under NetBSD. Still to do:
- bus-ify.
- bpf support.
- multicast support.
