Using RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment, it also prevent uCode encounter TX FIFO underrun and other HT mode related performance issues.

PCI bridge. ( http://patchwork.kernel.org/patch/53004/ ) This patch fixes entry #1. "1. p54p_check_rx_ring - skb_over_panic: Under a ping flood or just left running for a bit would panic with a skb_over_panic." As described in the mail: The invalid frame length causes skb_put to bailout and trigger a crash. Note: Simply dropping the frame is problematic, because if its content contains a tx feedback we would lose some portion of the device memory space.... And the driver/mac80211 should handle all other invalid data. Reported-by: Quintin Pitts Signed-off-by: Christian Lamparter Signed-off-by: John W.
