From 1542272a60ab9c0655a13ead8b7d7a661365f9fb Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 14 Dec 2005 12:55:24 -0800 Subject: [GRE]: Fix hardware checksum modification The skb_postpull_rcsum introduced a bug to the checksum modification. Although the length pulled is offset bytes, the origin of the pulling is the GRE header, not the IP header. Signed-off-by: Herbert Xu Signed-off-by: David S.
