[PATCH 2/3] realtek: sort the port list numerically

[Bjørn Mork]

Mac adresses are assigned in the order given by the port list.  The
interfaces are also brought up in this order.  This target supports
devices with up to 52 ports.  Sorting these alphabetically is very
confusing, and assigning mac addresses in alphabetic order does not
match stock firmware behaviour.

There are probably better ways to do the numrical sorting, but this
was what I came up with...
