In looking around at other implementations, I see where the link_up
and link_down are used to start or clean up the periodic workqueue
used to retrieve and accumulate the mib stats into the driver.  Can't tell
if that's a requirement or only needed when the device interface is
considered too slow.  The device interface is not atomic.
