[rt2x00-users] [RFC 1/3] rt2x00: configure tx queues for APs that do not support 802.11e

[Stanislaw Gruszka]

Old APs, which do not support QOS, need to have old DCA rules
configured for each EDCA tx queue.

Patch configure 11g channel access rules for now, because it is not
trivial to check if we operate on 11b only mode.
