mac80211: add rate control rewrite and enhance the performance of the minstrel algorithm for non-mrr configurations SVN-Revision: 12948
2008-10-11 01:33:09 +00:00
Subject: mac80211: move bss_conf into vif
Move bss_conf into the vif struct so that drivers can
access it during ->tx without having to store it in
the private data or similar. No driver updates because
this is only for when they want to start using it.
