It makes the upstreaming process easier for us since we normally work
out of tree and then upstream patches after testing in the case of
i40e.

Yeah, I'll be working on providing headroom in order to support
build_skb anyway so I can just combine the efforts.  Then it makes the
upstreaming effort easier as well as we will have the headroom added
before we actually start work on XDP.
