sys/cdefs.h. In particular, in case of COMPAT_43, param.h includes
sys/types.h, which includes sys/select.h, which includes
sys/_sigset.h. The _sigset.h customizes the provided definions based
on COMPAT_43, eliminating osigset_t if symbol is not defined. The
sys/proc.h is included after opt_compat.h and needs osigset_t.
Move opt_compat.h inclusion into the right place.

the bio is unmapped, so we must map the bio pages into pbuf. This
works around the geom classes which do not follow the MAXPHYS limit on
the i/o size, since such classes do not know about unmapped bios
either.

o Only vt_core module use compat options, move it from common header to module.

o Include opt_splash.h for vt(9) to know when splash device is enabled.
o Build logo_freebsd.c only if splash and vt are enabled.
o Include opt_compat.h to know when we have to respect compatibility.

The code was unmodified compared to Linux and returned the amount of
received bytes from the i2c bus. This led to non-working i2c bus and
failure to eg. read monitor's EDID, if connected to DisplayPort.

This fixes radeon_agp_init() and gtt_size is now correct. However, this
is not enough to make Radeon AGP cards work: ttm_agp_backend.c isn't
implemented yet.

Make the scan state optional - we'll obviously need a vap, but we now
won't require the scan state. the only thing the scan state is needed
for is to check for the list of SSIDs to scan - which we can now
just plain ignore by passing in NULL as the scan state pointer.
Tested:
* Intel 5100 (STA)
This is in preparation for being able to use iwn_scan() to do an off
channel scan to reset the RF tuning.
It should be a no-op.
Tested:
* Intel 5100 (STA)
in preparation for the scan based retune logic.
The linux iwlwifi driver does a rescan (onto a non-active channel)
to force an RF retune when the PLCP error rates exceed a certain threshold.
* Add code to track HT PLCP rate errors;
* Separate out the PLCP error count fetch and update so the delta
can be used when checking for PLCP error rates;
* Implement the PLCP error logic from iwlwifi;
* For now, just print out whenever the error rate exceeds the
threshold.
The actual scan based retune will take a bit more effort; the scan
command code right now assumes that a scan state is passed in.
This does need to change to be more flexible (both for this and
in preparation for scanning multiple channels at once.)
Tested:
* 5100 (STA mode)
* 2200 (STA mode)
* 2230 (STA mode)
working on some RF tuning issues.
The linux iwlwifi driver has these thresholds which they use to see
if there are PLCP errors over a certain interval. If they hit this,
they trigger a single-channel (different from active channels!)
scan to retune the RF front-end.
- Add support to 40Gbps devices;
- Add support to control adaptive interrupt coalescing (AIC)
via sysctl;
- Improve support of BE3 devices;
Many thanks to Emulex for their continued support of FreeBSD.

scheduling classes in the chip and to bind tx queue(s) to a scheduling
class respectively. These can be used for various kinds of tx traffic
throttling (to force selected tx queues to drain at a fixed Kbps rate,
or a % of the port's total bandwidth, or at a fixed pps rate, etc.).
