tl;dr - just enable dhcpcd in rc.conf without any specific interface

You can treat it as a normal non wired network interface and either
run 'dhcpcd urndis0' or just have dhcpcd running and let it pick it up
automatically.
If you have wifi and urndis0 both active dhcpcd will prefer the
"wired" one (urndis0), which is typically the behaviour you want.

I've been tethering NetBSD from android phones seemingly ~forever and
its been a life saver. Sometimes I find a public wifi that my NetBSD
laptop does not like, and I can just connect to it on my phone, then
USB tether to the laptop (which also charges :)
