openwrt/package/kernel/mac80211/patches/603-rt2x00-introduce-rt2x00eeprom.patch
Gabor Juhos 6c29525f42 mac80211: add a bunch of rt2x00 specific changes 
Backport some rt2x00 specific changes from
wireless-testing/master-2013-08-26 to add
support for RT3573 based devices.

Also refresh the rt2x00 specific patches.
