-Clean up the tx status reporting, fix retry counters (short retries are
-virtual collisions, not actual retries). Implement multi-rate retry
-support.
-This also fixes strong throughput fluctuations with rc80211_pid

+Fix the b43 tx status reporting.
+
+If the hardware uses RTS/CTS reporting and the actual RTS/CTS
+handshake failed, it will switch to the fallback rate, even
+though the main rate was never actually attempted.
+Make sure that this does not screw up rate control statistics.
