That patch seems to be adding only WPA_IF_STATION type interfaces which
would be fine for another station, but maybe not ideal for AP. Could you
please clarify why this functionality should be in wpa_supplicant?
Since driver_nl80211.c is tracking interfaces added and removed through
if_add() and if_remove() some of these operations triggered by external
control could result in unexpected results. As such, this does not look
like the safest way of addressing a need to add/remove a virtual
interface for independent of internal wpa_supplicant needs. If I
understood the use case correctly, doing this without storing any state
in driver_nl80211.c for the interface that was used to remove/add and
interface could be more appropriate for this.
