From 64261f230a9157f5f520ce30ec6827d679375e2f Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Tue, 13 Aug 2013 17:51:09 +0200 Subject: [PATCH] dev: move skb_scrub_packet() after eth_type_trans() skb_scrub_packet() was called before eth_type_trans() to let eth_type_trans() set pkt_type. In fact, we should force pkt_type to PACKET_HOST, so move the call after eth_type_trans(). Signed-off-by: Nicolas Dichtel Signed-off-by: David S.
