From acc81e1465d29e0284008770cc4b8bc90bd93bd7 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Tue, 8 Jul 2008 03:21:27 -0700 Subject: vlan: fix network_header/mac_header adjustments Lennert Buytenhek points out that the VLAN code incorrectly adjusts skb->network_header to point in the middle of the VLAN header and additionally tries to adjust skb->mac_header without checking for validity. The network_header should not be touched at all since we're only adding headers in front of it, mac_header adjustments are not necessary at all. Based on patch by Lennert Buytenhek .
