Thanks! This looks reasonable. I did some cleanup and applied it.

Based on a quick test, this seemed to be able to connect over 100
station vifs using WPA2-Personal to a single AP without major problems.
Some resources are running out (just CPU?) that makes some of the 4-way
handshakes fail (timeout?), but after couple of tries, I got 116 of
124 stations connected. This is with all interfaces starting at the
same time; using some more latency there would likely make this quite a
bit more robust.

wpa_supplicant seemed to stop trying to reconnect in some cases, so this
probably triggered some bugs that need to be addressed. Anyway, manual
"wpa_cli -i<ifname> reassociate" on the missing eight vifs was able to
get all the 124 stations connected at the same time.
