From 42c5e15f18d63c1ecf79d52bdaf4ea31cd22416d Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 2 Feb 2006 16:53:26 -0800 Subject: [PATCH] [NET] snap: needs hardware checksum fix The SNAP code pops off it's 5 byte header, but doesn't adjust the checksum. This would cause problems when using device that does IP over SNAP and hardware receive checksums. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
