Allow specifying the xfrm interface if_id as part of a route metadata using the lwtunnel infrastructure. This allows for example using a single xfrm interface in collect_md mode as the target of multiple routes each specifying a different if_id. With the appropriate changes to iproute2, considering an xfrm device ipsec1 in collect_md mode one can for example add a route specifying an if_id like so: ip route add <SUBNET> dev ipsec1 encap xfrm if_id 1
It would be nice to be able to specify the link also. It may help to combine this with vrf. Something like ip route add <SUBNET> dev ipsec1 encap xfrm if_id 1 dev eth0
