Hi all,

If you're an AR9285 or AR2427 user, please try the very latest -HEAD ath driver.

I've added controllable software RX diversity (which seems to be the
last bit of the "weird throughput" problems) - you can select it by
the very badly named txantenna sysctl. Sysctl dev.ath.0.txantenna = 0
means "enable both and do fast diversity on RX", = 1 means "favour
antenna A", = 2 means "favour antenna 2."

I'll figure out a better way of controlling this (likely by just
overriding the RX antenna control method) in the future.

This seems to have resolved all the issues I've had with the AR9285 and AR2427.

Thanks,


Adrian
