[PATCH 5/7] Minor final fixes.

[Milan Plzik <milan.plzik@gmail.com>]

- report rate at which was frame received
- fix the issue with growing latencies (call ieee80211_wake_queues from tx
  complete handler)
- tx handler doesn't report ack'ed frame anymore -- the adapter doesn't
  report ACK status
- association after loading driver now works at first attempt
