After resume the status is "Disabled".

The workaround, a file called "unload_modules" in /etc/pm/config.d, with the following value "SUSPEND_MODULES="$SUSPEND_MODULES tg3"" seems sometimes to work.
Without the workaround almost every restart did not start the net, with the WA the network starts sometimes but not always.
