Hello,

I'm using a fairly recent, and fairly hacked upon hostapd, with a modified 4.20 kernel.

I set up two AP interfaces on two radios on two machines (8 hostapd total),
and clustered them as an 802.11r cluster.

I started two station interfaces on a separate system and have them roam between
the vap every 10 or so seconds.  After around 10 roams total, I start getting
roam failures due to 'code-17' response.

I debugged the AP system, and the kernel is rejecting the station-add, due to this
logic below.  In the failure case, statype is 0, which is ap-client.

Looks like this is related to PMF/MFP.  When that is disabled, it works nicely.

I'll have to try with some ath9k systems to try to understand if it is related
to ath10k or not...

Thanks,
Ben
