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
