Look in the archive of the "netdev" mailing list for "netlink".

However, the netlink messages are only generated when the driver 
detects the link up/down event. For 3c59x driver, this is timer 
driven, so it might take some time (up to 60 seconds for MII capable 
cards) from the time the link has change state until the situation is 
detected.
