So it seems heavy load of RX can cause problems with TX. I just though
of one another reason, could you test one more thing for me?

Edit drivers/net/wireless/b43/dma.h and change define from value 64 to
in the line:
#define B43_RXRING_SLOTS		64

Can you get "Out of order TX" much more easily after such a change?
