Can't find anything more to complain about :)

Ran a quick performance test: On a test using xdp_redirect_map from
samples/bpf, which gets 8.15 Mpps normally, loading an XDP egress
program on the target interface drops performance to 7.55 Mpps. So ~600k
pps, or ~9.5ns overhead for the egress program. So other than the nit in
the bpftool patch, please consider the series:
