When the genIE hasn't changed there's no reason to kick the state machine since it won't be able to do anything new -- doing this decreases the useless work we do for reassociating because if we do kick the state machine it will try to find a usable BSS but there might not be one because wpa_supplicant will only change the BSSID a little later. In a sense this is a workaround for userspace behaviour, but on the other hand userspace cannot really keep track of what the kernel currently has for genIE since any process could have changed that while wpa_supplicant wasn't looking.
