OK thanks. Would building it the same on the bhyve *host* have an effect?
I'm asking because you earlier mentioned it's a vm-friendly change.

I can test this if you like. I'm wondering if some changes on the host also
change the vm throughput. The host is currently using rack but the kernel is
older than your changes. The host has expected throughput for 1GiB ethernet
right now. Everything in the tests apart from the test target had the default
params for the ethernet interface, so things like TSO are enabled.

How can I apply your commit into a local 14.1-p5 src tree? I think this is
called 'cherry picking' but I don't really know much about git at all.
It'd be interesting to test, i think.
