>     Starting from NVM 5.02, if the Set Local LLDP MIB command is
>     received while the DCBx specific agent is stopped, the command
>     returns an EPERM error. If the command is received while the
>     LLDP agent is stopped, it sets the local MIB without exchanging
>     LLDP with peer, and returns SUCCESS.

> So, if possible (older firmwares cannot safely stop LLDP), stop the lldp daemon
> when we are in software mod before we attempt to call i40e_set_dcb_config.
