(That last paragraph above is why I asked if you updated the performance
numbers in the cover letter; removing an additional function call should

Yeah, it should. Let me spend some more time benchmarking on the DEVMAP
scenario.
I did a re-measure using samples/xdp_redirect_map.
The setup is 64B packets blasted to an i40e. As a baseline,
# xdp_rxq_info --dev ens801f1 --action XDP_DROP
gives 24.8 Mpps.
Now, xdp_redirect_map. Same NIC, two ports, receive from port A,
redirect to port B:
baseline: 14.3 Mpps
this series: 15.4 Mpps
which is almost 8%!
