| H A D | if_ath_rx_edma.c | diff 238432 Sat Jul 14 00:19:29 MDT 2012 adrian Fix EDMA RX to actually work without panicing the machine. I was setting up the RX EDMA buffer to be 4096 bytes rather than the RX data buffer portion. The hardware was likely getting very confused and DMAing descriptor portions into places it shouldn't, leading to memory corruption and occasional panics. Whilst here, don't bother allocating descriptors for the RX EDMA case. We don't use those descriptors. Instead, just allocate ath_buf entries. |
