For now, if the XDP prog returns XDP_PASS on XSK, the metadata
will
be lost as it doesn't get copied to the skb.

I have an urge to add a newline here, when reading this, as IMHO it
is a 
paragraph with the problem statement.

Copy it along with the frame headers. Account its size on skb
allocation, and when copying just treat it as a part of the frame
and do a pull after to "move" it to the "reserved" zone.

Also newline here, as next paragraph are some extra details, you
felt a 
need to explain to the reader.

net_prefetch() xdp->data_meta and align the copy size to speed-up
memcpy() a little and better match i40e_costruct_skb().

Oh gosh, I thought I don't have attention deficit. Thanks, maybe
Tony will fix it for me or I could send a follow-up (or resend if
needed, I saw those were already applied to dev-queue).

If there's no need for follow-ups beyond this change, I'll fix it up.

Thanks,
Tony
