This boolean controls if the LLDP MIB change\nevents are registered for. Also, add a new function\ndefined ice_cfg_lldp_mib_change. The additional function\nis necessary to be able to register for LLDP MIB change\nevents after calling ice_init_dcb. The net effect of these\ntwo changes is to allow a delayed registration for MIB change\nevents so that the driver is not accepting events before it\nis ready for them.\n\nSigned-off-by: Dave Ertman
