New Revision: 220029
URL: http://svn.freebsd.org/changeset/base/220029
Log:
Add in the hardware PS-POLL frame reception setting, but leave it disabled
by default.
Adventourous souls with an AR9220/AR9280 or later and who have a device
that sends PS-POLL frames may wish to try tinkering with this option and
get back to me.
