From: "Gabriel L. Somlo" <gso...@gmail.com>
Generate a link status change interrupt once link auto-netotiation
is successfully completed. This does not affect Linux and Windows
(XP and 7 tested) in any way, but is needed by the stock OS X driver
(AppleIntel8254XEthernet.kext), which would otherwise fail to notice
the link status change event.
