Issues roaming to same AP over and over.

[Ben Greear]

I have a stress test that roams 10 stations to the AP they are already connected to
every 5 seconds.  I'm using wpa_cli to cause the scan and roam to happen.
When it works right, they successfully reconnect most of the time.

But, often it gets into a state  where I see 'iw' messages like this below and
I am not sure it ever recovers.

If I 'reset' the ports, telling supplicant to reconfig, etc, then it recovers
for a while.

Any idea what might be wrong?
