sunvnet: add stats to track ldom to ldom packets and bytes
In this driver, there is a "port" created for the connection to each of
the other ldoms; a netdev queue is mapped to each port, and they are
collected under a single netdev. The generic netdev statistics show
us all the traffic in and out of our network device, but don't show
individual queue/port stats. This patch breaks out the traffic counts
for the individual ports and gives us a little view into the state of
those connections.
