Subject: rtl8192se: ping router gives mdev of 25387.102???

Hi everyone,

(please cc)

see $subject ...

No warning, nothing in the logs, but pinging my router I get
things like:
--- 192.168.0.1 ping statistics ---
376 packets transmitted, 315 received, +33 errors, 16% packet loss, time 405164ms
rtt min/avg/max/mdev = 0.873/10077.793/95935.698/25387.102 ms, pipe 68

or
--- 192.168.0.1 ping statistics ---
1252 packets transmitted, 1225 received, 2% packet loss, time 1252976ms
rtt min/avg/max/mdev = 0.941/764.171/19929.265/2758.225 ms, pipe 20


Has anyone *ever* seen a mdev of 25387.102 ms ???

At the same time I am pinging the same router from an iphone with a 
steady stream of 40ms or so, no problem whatsoever ...
