From bbf4a6bc8c4d59a0a9033fc2cb96ec03430c96e4 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 13 Feb 2007 12:32:58 -0800 Subject: [NETFILTER]: Clear GSO bits for TCP reset packet The TCP reset packet is copied from the original. This includes all the GSO bits which do not apply to the new packet. So we should clear those bits. Spotted by Patrick McHardy. Signed-off-by: Herbert Xu Signed-off-by: David S.
