[PATCH] mac80211: defines for AC numbers

[PATCH] mac80211: defines for AC numbers

[Johannes Berg]

From: Johannes Berg <johannes.berg@intel.com>

In many places we've just hardcoded the
AC numbers -- which is a relic from the
original mac80211 (d80211). Add constants
for them so we know what we're talking
about.
