From 4c6d4f5c33fbe19b134c1af43af166fee79eb986 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Thu, 16 Jul 2009 10:05:41 -0700 Subject: mac80211: add helper for management / no-ack frame rate decision All current rate control algorithms agree to send management and no-ack frames at the lowest rate. They also agree to do this when sta and the private rate control data is NULL. We add a hlper to mac80211 for this and simplify the rate control algorithm code. Developers wishing to make enhancements to rate control algorithms are for broadcast/multicast can opt to not use this in their gate_rate() mac80211 callback.
