lwtunnel: set skb protocol and dev
In the locally-generated packet path skb->protocol may not be set and this is required for the lwtunnel encap in order to get the lwtstate. This would otherwise have been set by ip_output or ip6_output so set skb->protocol prior to calling the lwtunnel encap function. Additionally set skb->dev in case it is needed further down the transmit path. Signed-off-by: NRobert Shearman <rshearma@brocade.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
