oh, that's neat, I wasn't aware of that! So it didn't use the 11s implementation in mac80211 in the Linux kernel? Oh wait, back then there wasn't even mac80211 yet, I guess.
Did the Marvel chip use some extra firmware for that? Or was it burned into the chip, with no option to update the algorithm?
That now makes me wonder, if the firmware for Qualcomm and Mediatek Wifi chips were OpenSource / reverse engineered if they could be used similarly.
