New Revision: 321752
URL: https://svnweb.freebsd.org/changeset/base/321752
Log:
MFC 321406
ethernet: Add ethernet interface attached event and devctl notification.
ifnet_arrival_event may not be adequate under certain situation; e.g.
when the LLADDR is needed. So the ethernet ifattach event is announced
after all necessary bits are setup.
