number of peers exceeded after a short time

[Conrad Kostecki]

Hi!

I am using hostapd 2.3 with 2x ath10k (WLE900VX, FW 10.2). Kernel is 3.18.0.
Four SSIDs are being broadcasted. Two directly from ath10k and another two via a vif, based on the real ath10k-interfaces.
Two SSIDs are using WPA2 and two other are using WPA2-Enterprise.

This problem started for me since upgrading vom Kernel 3.17.x (FW 10.1) to Kernel 3.18.0 (FW 10.2). When I downgrade, it happens much less..

After a very short time, about 5-15 minutes, my dmesg is beeing logged full with those messages:
[2055815.205855] ath10k_pci 0000:0c:00.0: number of peers exceeded: peers number 127 (max peers 127)
[2055818.796016] ath10k_pci 0000:0c:00.0: number of peers exceeded: peers number 127 (max peers 127)
[2055822.392301] ath10k_pci 0000:0c:00.0: number of peers exceeded: peers number 127 (max peers 127)
[...]

How is this possible? This is my private home router. I've only a few wifi devices.
I've noticed, that this problem mainly happens, when my Nokia Lumia 930 tries to connect with my WPA2-Enterprise network.

Is this a ath10k problem, which is not correctly processing the peers or hostapd?

Cheers
Conrad
