From 173021072e86a0a5b3d2271347493a3e0d5f68e8 Mon Sep 17 00:00:00 2001 From: Changli Gao Date: Mon, 20 Dec 2010 04:35:30 +0000 Subject: net_sched: always clone skbs Pawel reported a panic related to handling shared skbs in ixgbe incorrectly. So we need to revert my previous patch to work around this bug. Instead of reverting the patch completely, I just revert the essential lines, so we can add the previous optimization back more easily in future. commit 3511c9132f8b1e1b5634e41a3331c44b0c13be70 Author: Changli Gao Date: Sat Oct 16 13:04:08 2010 +0000 net_sched: remove the unused parameter of qdisc_create_dflt() Reported-by: Pawel Staszewski Signed-off-by: Changli Gao Acked-by: Eric Dumazet Signed-off-by: David S.
