madwifi & AP

MadWifi currently provides four different rate control algorithms,
ONOE, AMRR, SAMPLE and MINSTREL. SAMPLE and MINSTREL are both very
advanced, but MINSTREL is quite new. Consequently, SAMPLE is used by
default. In order to make MadWifi use e.g. AMRR instead, you have to
specify that as the module parameter e.g.

# modprobe ath_pci ratectl=amrr

NOTE: Changing the rate control is only required (and recommended) for
users who want to setup an access point using MadWifi in difficult
(e.g. lossy) environments and who know what they are doing.
