Hmm, in one direction anyway?

NetBSD current testing on a RPi4 for
iperf3 -R -c 192.168.1.120 -B 192.168.1.140 :

This is faster than the built-in EtherNet results.
(But the built-in is also USB based.)

As for iperf3 -c 192.168.1.120 -B 192.168.1.140 it is
slower:

This is again faster than the built-in EtherNet results.
