This series implements support for layer 3 ports, of which we have one example so far, the LISP vport. LISP support is currently implemented with a hack, by adding/removing the Ethernet header within the datapath/vport-lisp.c file. By removing the assumption that all packets/flows have Ethernet header, this series adds generic support for layer 3 ports in OVS, and thus it is expected that the user/kernel space API for LISP support will not change. This will allow the upstreaming of the LISP vport, resulting in a decreased the delta against the Linux kernel module, which is the goal that started this work. It will also allow supporting layer 3 GRE tunnels, for which patches have been proposed based on this work.
The patch set doesn't change the current behavior when a packet from a LISP port is sent to a layer 2 port or the other way around, so it's not necessary to change existing flow rules. The implementation will automatically add the appropriate pop_eth and push_eth actions to datapath flows. This may change in the future when OpenFlow support for these actions will be added, since discussions on EXT-112 in the ONF showed preference for explicitly requiring the pop_eth and push_eth actions in OpenFlow rules.
