From f466dba1832f05006cf6caa9be41fb98d11cb848 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Wed, 23 Dec 2009 22:02:57 -0800 Subject: pktgen: ndo_start_xmit can return NET_XMIT_xxx values This updates pktgen so that it does not decrement skb->users when it receives valid NET_XMIT_xxx values. These are now valid return values from ndo_start_xmit in net-next-2.6. They also indicate the skb has been consumed. This fixes pktgen to work correctly with vlan devices.
