the current code in wireless-testing uses SWBA not to send beacons but to keep
track of the next beacon time NBTT. this is necessary to work around certain
hardware limitations. once configured, the beacons are sent automatically by
the hardware at the right time. of course it would be possible to change the
code to generate a new beacon at every SWBA but as long as the beacon
contents don't change very often i don't see the point of doing so.

i don't know how you come to that conclusion - ath5k *is* in wireless-testing
and there are a few people working on it.
