> There is a bug where the LFC settings are not being preserved through a link
> event.  The registers in question are the ones that are touched (and
> restored) when a set_local_mib AQ command is performed.
> 
> On a link-up event, make sure that a set_local_mib is being performed.
> 
> Move the function ice_aq_set_lldp_mib() from the DCB specific ice_dcb.c to
> ice_common.c so that the driver always has access to this AQ command.
