I don't agree on this.
Fwd config should be only changed after the user change something like
nb-cores, queue number, eth-peer in non-dcb mode. These are already done in
those commands.
You should do fwd_config_setup at the end of cmd_config_dcb_parsed(), I agree
on this.
But doing it in start port seems to do redundant times of fwd_setup. It's not
really needed.
