Just 'ifconfig qwx0 debug' doesn't give any output (terminal or
console). I don't know if it should. The commands 'ifconfig qwx0 down;
ifconfig qwx0 up debug' resulted on console:

Did not succeed in reproducing so far. I tried a network without a
mention of "802.1x", namely from
detekti# ifconfig qwx0 scan
qwx0: flags=808847<UP,BROADCAST,DEBUG,RUNNING,SIMPLEX,MULTICAST,AUTOCONF4> mtu

I selected 'gast-bonnet':
detekti# ifconfig qwx0 join gast-bonnet debug
detekti# ifconfig qwx0
qwx0: flags=808806<BROADCAST,DEBUG,SIMPLEX,MULTICAST,AUTOCONF4> mtu 1500

Nothing on console from these commands. I cannot reproduce the error.
Additional dmesg output that seems to be new:
qwx0: missed beacon threshold set to 30 beacons, beacon interval is 100 TU
qwx0: failed to enqueue rx buf: 28
qwx_ce_recv_process_cb: failed to post rx buf to pipe: 2 err: 28
I will try my networks at home tonight and try to reproduce the error
and generate debug output...
I am running the latest snapshot (same as for original report).
