[committed on behalf of sephe]
- Add {TAILQ,STAILQ}_CONCAT() macros
- Add comment about *_FOREACH_MUTABLE()
- Sync ath(4) with FreeBSD (sam@freebsd.org):
o Add/Correct some debug information.
o Add more statistics.
o Receive control frames in monitor mode.
o Close race in handling mcast traffic when operating as an ap with
stations in power save: add a new q where mcast frames are stashed
and on beacon update (at DTIM) move frames from the mcast q to the
cabq and start it. This ensures the cabq is only manipulated in
one place.
o Correct the type of ath_descdma.dd_desc_len
o Correct max segement size when creating DMA tag
