From 6088a539d8d1666dca6979b5759bf966ee9124ef Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 27 Feb 2010 19:41:42 +0000 Subject: [PATCH] bridge: Use BR_INPUT_SKB_CB on xmit path this patch makes BR_INPUT_SKB_CB available on the xmit path so that we could avoid passing the br pointer around for the purpose of collecting device statistics.
