Hi Martin,

It is great to see work in this area.

Push/pop of headers is listed as on of the missing features here:
 https://prototype-kernel.readthedocs.io/en/latest/networking/XDP/implementation/missing_features.html
We can hopefully soon cross that of the list :-)

Header push and pop desc:
 https://prototype-kernel.readthedocs.io/en/latest/networking/XDP/design/requirements.html#header-push-and-pop

Thanks for working on this! :-)))
