Hi! There's a couple of things I can think of.
Firstly, it'd be nice if we had per-packet TPC working on some of those earlier chips. Then you could throw in TX power into the mix. Secondly, yes - you can do per-packet TX antenna selection on these NICs. You could modify the rate control API in mac80211/ath5k to let you "walk" the list of available antennas and do some probing to determine which antenna gives you the lowest PER or something. The BSD/madwifi ath(4) driver would do dynamic antenna selection (which worked on for STA mode, kind of) which would look at the antenna selected by the hardware on RX and use that as the default.. it leveraged using fast antenna diversity on the chip and paid attention to which antenna the hardware would choose. I don't know how much of that code is left in ath5k; it however is based on RX rather than TX statistics. It's useful to look at though.
