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.
