Hi Johannes,
I tested the patch on kernel 2.6.32.7 with compat-wireless-2010-03-03 but
it seems that the problem is not solved. If I set the lowest priority queue
(Backgreound), the system will crash for an out of memory panic. During the
tests I carried out, I transmit 50Mbps UDP traffic.
Regards
Lorenzo
