Adrian Chadd 67aaf73997 Modify the RX path to keep the previous RX descriptor around once it's ... used. It turns out that the RX DMA engine does the same last-descriptor-link- pointer-re-reading trick that the TX DMA engine. That is, the hardware re-reads the link pointer before it moves onto the next descriptor. Thus we can't free a descriptor before we move on; it's possible the hardware will need to re-read the link pointer before we overwrite it with a new one. Tested: * AR5416, STA mode TODO: * more thorough AP and STA mode testing! * test on other pre-AR9380 NICs, just to be sure. * Break out the RX descriptor grabbing bits from the RX completion bits, like what is done in the RX EDMA code, so .. * .. the RX lock can be held during ath_rx_proc(), but not across packet input.		2014-05-06 01:15:42 +00:00
