Hopefully Luis will be allowed to release his efforts in a form that can be incorporated into
the stock kernel source.

At the moment the semi-free madwifi is more reliable than ath5k with 2.6.25-rc kernels[*], due
(I suspect) to problems with the mac80211 layer being rather too aggressive in reducing the
link speed in face of less than ideal signal conditions. Signal quality/level monitoring
(using wavemon) suggests that unsmoothed values are causing the rate algorithms to believe
that conditions are worse than they actually are. I see similar problems with the in-kernel
rt2500 driver.

[*] Incidentally, the 2.6.25-rc8 ath5k driver doesn't install, due to symbol mismatches.
compat-wireless does work.

Ah.  An explanation for my rt2500pci mac80211-based driver falling back to low speeds and
requiring a 'iwconfig' at the command to get the device back to full speed.  Thank you!

It appears to be tweakable via debugfs. Linux Wireless Wiki

That's what the man said in the article, that Atheros is trying to get driver support into the
vanilla kernel.
