Bridge, promiscous mode andCPM2

Assuming CPM2 => 82xx or 85xx CPU.

In the old 8260_io/fcc_enet.c	the set_multicast_list 
function is present, bu has an early return nine lines 
in. If you delete that return, promiscous mode works great.

I have no idea who or why that early return was put in, 
but it does disable multicast and promiscous mode 
on the FCC ethernets.
