From c6a1b62de9d043f274ec3ae2e207908c6d5feff3 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 7 Jan 2008 00:23:04 -0800 Subject: [PATCH] [TULIP]: NAPI full quantum bug. This should fix the kernel warn/oops reported while routing. The tulip driver has a fencepost bug with new NAPI in 2.6.24 It has an off by one bug if a full quantum is reached.
