Do you > foresee this happening? right now, probably none. but it's easy to this to ath5k. madwifi supported it and it's just a matter of setting tx and rx antennas (it's already there as AR5K_ANTMODE_DEBUG). i might add it, just to make my case... ;) anyhow, i can see your point of view now. but while you might not care about anything before 802.11n - there are millions of what you call 'legacy' chips out there (and you guys are actually still selling them!), so i think it's worth it to properly support them, especially since i still believe that my proposal is usable for both 802.11n and before. bruno
