> introduce the ice_build_skb responsible for it. Make use of XDP's data_meta

> I've observed around 30% less CPU consumption with build_skb Rx path, in
> comparison to legacy Rx. What stands behind such result is the avoidance of
> flow_dissector (which we were diving into via eth_get_headlen) and no
> memcpy calls.
