This is configured in sys/kern/subr_disk.c. You can hardcode some of your
ethernet ports (e.g., cnmac0) there. However take if you use the same source
tree to build to compile from other archs than octeon, because this file is
used in all archs. Be sure to put your changes inside #ifdef CPU_OCTEON .
I have this in my tree, but take it at your own risk and to be clear: it is a
nasty workaround. The only use case for my EdgeMax is for hacking. I would not
use them in production until USB supported be concluded, but it is up to you.
