When PF is reset, a message will show it.
User can run the command "port reset port_id"
to reset the VF port and to keep same port id without any
without any configuration.
And then user can run "start port_id" to reconfigure
its forwarding mode and parmaters as previous.
To avoid crash, current forwarding should be stopped.
