See desc.c...
"AR5K_TXERR_XRETRY" - excessive retries (with no ack)
"AR5K_TXERR_FILT" - the frame was filtered by matching a destination
mask - I don't think we use this tx filter
"AR5K_TXERR_FIFO" - couldn't DMA the frame to hardware fast enough

See RATE DEFINITIONS in ath5k.h - I think it's fairly well
documented.

The rate for which transmission actually succeeded.
