====================
lwtunnel: encap locally-generated ipv4 packets

Locally-generated IPv4 packets, such as from applications running on
the host or traceroute/ping currently don't have lwtunnel output
redirected encap applied. However, they should do in the same way as
for forwarded packets and this patch series addresses that.
