Doing this would let 3945 take advantage of all the d80211 features, so why not?
What level of fullmac support are we talking about? True fullmac cards (as I define them) do not need to use d80211. WE19 is all they need, to add WPA/WPA2 support. The IPW cards have a particularly unique split between firmware and host 802.11 duties which I haven't seen in any other cards. They aren't quite fullmac enough to interface with WE directly, yet they only need probe response handling to complete the picture. What other half-fullmac, half-softmac card besides the other IPW cards splits card/host 802.11 duties along those lines? What other splits between card and host are out there? I would be very reluctant to make changes to the 802.11 stack to support "fullmac" without evidence that other drivers need the change. -Michael Wu
