Re: genet0 speeds under NetBSD/aarch64 on Rpi4 8 GB using UEFI/ACPI v1.17 firmware

Addendum:

I tried another receiving test using a different server on the same network (my pfSense gateway) and I did get better numbers than from the laptop:

iperf Done.

The average speed is better here, but there is still a lot of variation over the course of the test.  Also, it's still way slower than what I got using Raspberry Pi OS. :-(
