Hi Ran

The Marvell driver makes each port act like a normal Linux network
interface. So if you want to enable a port, do

ip link set lan0 up

Want to add an ip address to a port

ip addr add 10.42.42.42/24 dev lan0

Want to bridge two ports

ip link add name br0 type bridge
ip link set dev br0 up
ip link set dev lan0 master br0
ip link set dev lan1 master br0

Just treat them as normal interfaces.
