Author: adrian Date: Sat Mar 26 10:47:17 2011 New Revision: 220027 URL: http://svn.freebsd.org/changeset/base/220027 Log: Introduce hardware PS-POLL support in the HAL. Linux ath9k only enables this for AR9280 and later NICs; so create a capability for it so it isn't enabled for earlier NICs. Enabling hardware PS-POLL support will come in a later commit and will be disabled by default.
