[PATCH] sky2: receive queue watermark tweak
This patch makes the receive performance on some systems go from 714MB/s to 941MB/s. It adjusts the watermark of the receive queue to be lower, thereby avoiding excess hardware flow control. This is most important on the systems which have little/no additional buffering. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
