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