From 7a36df8a857edee8cd8967cbe99a85574d22f482 Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Sat, 25 Dec 2010 07:39:59 +0000 Subject: epic100: hamachi: yellowfin: Fix skb allocation size Joel Soete reported oopses during pppoe over sundance NIC, caused by a bug in skb allocation and dma mapping code, where skb_reserve() bytes weren't taken into account. As a followup to the patch: "sundance: Fix oopses with corrupted skb_shared_info" very similar code is fixed here for three other drivers.
