We've identified a need where it would be beneficial, via flow-mods, to be able to push an ethernet, or ethernet and IP, header onto a datagram. OVS already supports pushing an MPLS header, or VLAN tag, onto the datagram, so this seems a natural extension to the existing software.

We have two questions that make sense to put out into the community for comment:

1) Given that this function doesn't currently exist, is there a reason that it was intentionally not included when either the push_vlan or push_mpls actions were implemented?


2) If we were to offer a patch that provided the ability to do this, would it be received favourably and up-sourced into the main body of code?


Thanks!
