Update:
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.
This results in the harmless, but annoying, diagnostic:
default dcb config fails. err = -53, aq_err = 1.
So, always stop the lldp daemon when we are in software mode before
we attempt to call i40e_set_dcb_config.
