I booted freeBSD on the Raspberry pi, I was able to confirm that it used genet driver together with miibus for the NIC. This is further confirmed with the FreeBSD manual page. https://man.freebsd.org/cgi/man.cgi?query=genet
One more thing to follow is that i noticed that FreeBSD is using PSCI, so I'm assuming that it is being used for SMP. I'll file a ticket as soon as I'm able to grab more information.
