I have an e1000 card, and it does not need to rmmod before suspending.
But when I suspend/resume, there is a link down/up event like (only the
UP posted  here ): 
Feb  3 21:33:16 t41 kernel: e1000: eth0: e1000_watchdog: NIC Link is Up
100 Mbps Full Duplex

So NM sees a device with a link change to UP and tries to connect on it.
Isn't this the way it was supposed to happen ?
Why do we need more acpi events ?
