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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
