Fix bug in protocol parser that often caused fatal 'checksum error'.
Defer power save setting to interface start.
More verbose on errors.
Allow build without FDT.

Add OpenBSD to code to optionally load CLM (Country Locale Matrix) files.

bwfm: Switch from pcq to pool_cache.

pcq_get is required to be serialized, but it's far from clear that it
is serialized here.

Add include guards and appropriate includes to bwfmreg.h, bwfmvar.h.

No functional change intended.

discussed with thorpej@, and it seems it's better to allocate the bss
alignment buffer statically (as part of softc) just to be sure to not
affect performance

constify, and make static where possible

Add a file type entry for CLM files.

- Refactor the firmware loading code into a set of common routines in the
core driver that understand how to find model-specific files before the
generic files. This greatly simplifies the firmware loading procedure
in each of the bus front ends. Adding additional firmware file types
(such as CLM files) much simpler.
- Make firmware image selection table-driven rather than a set of switch()
and if() statements.
- Add several additional firmware image entries.

Add a few more chip ID.

More code from OpenBSD
no need to splnet() when enqueing packets
explicit structure padding
make internal functions static

also prepare for GPIO interrupts.

From OpenBSD:
- move event handling to workqueue
- check for save/restore capability
Tag work queue as MPsafe and increase length.
Juse use bpf_mtap(), the 802.11 encapsulation is handled by firmware.

bwfm has only one tx descriptor; limit mbuf chains to one segment.

Can't use m_defrag because it always yields two segments.
