Yeah, that's not going to work upstream, which is where we eventually want this to go... I think a fusion of the Intel and Nokia approaches is the best direction; taking the netlink communication approach from the Intel drivers, and the device-independence (and supplicant communication approach) from the Nokia drivers. Basically, WE is dead dead dead, and should no longer be used under any circumstances. A specific WiMAX netlink communications system should be used, like Intel has done. But there are still concerns upstream with the device-specificity of the kernel/userspace API as Intel has written it. I guess you guys just rewrote the Intel drivers, or wrote new drivers from scratch for the 2400 hardware?
