Yes, that's the main use case as far as I can see. Sorry for not being clear. The intention is to support tunnels that can have mixed L2+L3 traffic over a single lwtunnel interface. VXLAN-GPE already does this, this patch makes GRE behave identically, while preserving all current GRE users. The reason I sent this for net and not net-next is that I wanted to prevent the situation when we have a kernel released that supports ipgre lwtunnels but incompletely - i.e., ETH_P_TEB frames are discarded. But thinking about it more, it's probably non-issue. I'll retarget this patch for net-next and resend the first two for net. Thanks, Jiri
