Actually it doesnt make any difference if the cabling is connected at 
all for FreeBSD to detect the NICs. So, if the second NIC isn't listed 
it's probably because it's not supported in the kernel. I really can't 
tell more without seeing the actual dmesg output.

The uplink port on your switch is btw not supposed to be in MDIX mode 
when it is connected directly to a NIC (such as NIC2 on the monowall).

rlphy0 is the physical interface adapter for your rl0 NIC, and is not a 
NIC in itself.
