Basically the > reconfig is in ieee80211_reconfig() :) Wow, that's not exactly simple code; I expect it could be pretty difficult to get that right today on mwifiex. The current approach actually should be *easier* (for the kernel side) to avoid bugs, as it should be basically the same thing as 'rmmod'. Nonetheless, there are plenty of bugs.
