From c3905bc4b71ab562acf69765e8c4778bd263b9db Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 4 Dec 2006 17:08:19 -0800 Subject: [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.
