I have tested this patch as well and it looks correct. However, during
my test, the hardware does not set L2PAD flag, even if padding is
present (for some frames). I did the same test with the rt2870sta
driver from Ralink and the L2PAD was indeed set.
Ivo : what happens during your tests?
Regards,
Benoit
