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.
Here are the full dmesg log of Raspberry pi 4B booting FreeBSD 13.2
