Hmm, things could be much easier for rt2x00 if there was a mac80211 flag
that would indicate if the tx_status should be called or not upon txdone.

I used the IEEE80211_TX_CTL_READY_FOR_TX to make sure RTS and CTS frames
were not reported to mac80211 when they were send, but would it perhaps be
better if I used the flag IEEE80211_TX_CTL_REQ_TX_STATUS for that?
I remember that some time ago drivers weren't supposed to check for that
flag, or at least not to determine if the tx_status should be called, but has
this changed and can the flag be used or should rt2x00 keep track of what
should be reported and what not?
