From 6e532cfe49b6e961e1260642a44959b645e9ab54 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 9 Oct 2006 15:49:27 -0700 Subject: [PATCH] [PATCH] sky2: set lower pause threshold to prevent overrun Adjust the pause threshold on slower systems to keep from getting overrun. Since FIFO is 2K bytes, don't send XON pause until there is space for a full frame.
