Could you enable debugfs and use the tools here:
http://www-user.rhrk.uni-kl.de/~nissler/rt2x00/index.html

To create a dump of the frames as they are actually send out from the driver
to the hardware including the status report. This will tell if rt2x00 is actually
bringing the frame to the hardware correctly.

Packet filter flags of 2 sounds a bit restrictive.

Johannes, for Master mode shouldn't the following flags be set as well:
FIF_PROMISC_IN_BSS
FIF_CONTROL

Or should the driver enable those automatically when master mode is enabled?

I'm not sure what is happening here...
