New Revision: 237043
URL: http://svn.freebsd.org/changeset/base/237043
Log:
Disable BGSCAN for 802.11n for now. Until scanning during traffic is
fixed for 802.11n TX, this needs to be disabled or users wlil see randomly
hanging aggregation sessions.
Whilst I'm here, remove the warning about 802.11n being full of dragons.
It's nowhere near that scary now.
