Let swconfig provide the cpu port index in its help page. This is
needed as e.g. Atheros switches have their cpu port at port 0, not
port 5.
This could allow e.g. luci to get a rough overview of the layout of
the switch.

Swconfig needs to make sure that requested vlans/ports actually exist,
else it might read or modify memory not belonging to itself.
This patch adds a quick range check in swconfig's kernel part to
prevent accidential or intentional memory modification.
