You seem to know sources I don't know off. Could you please tell me,
where to find them?

I have DPO_RT5572_LinuxSTA_2.6.0.1_20120629 which doesn't compile with
HAS_CFG80211_SUPPORT=y because -DCONFIG_AP_SUPPORT, on which
RT_CFG80211_SUPPORT relies, is broken.

DPO_RT5572_LinuxSTA_2.6.1.3_20121022 removed the necessary broken AP
code completely.

I know.

I tried to show, why WEXT as a whole is still necessary even if there is
a mac80211 based driver, because of the weakness of rt2800usb:
Nip it in the bud.



Kind regards,
Andreas
