I think that decision was made without much consideration to the implementation details. I thought it was a good idea then, but passing messages from userspace to the kernel and then to userspace again is really a waste of time. NetworkManager already uses wpa_supplicant to avoid all the nasty details of dealing with wireless configuration, so why not keep using it for everything instead of hiding wpa_supplicant behind nl80211? This is more simple and direct and allows the kernel to expose exactly what the hardware/kernel can do. Userspace won't have to change much and nl80211 won't have to support every possible thing a userspace MLME would want. -Michael Wu
