Actually this require quite big changes in iwlegacy at least, perhaps also in iwlwifi. I prefer to revert commit as temporary fix, and add memset(0) to drivers .add_sta callback, in drivers which need it. After changing iwlegcy/iwlwifi we could move memset(0) back to ieee80211_reconfig(). Eliad, thoughts? > Should I just revert it?
