agent.\n\nSince reading LLDP configuration from NVM only gives information what\nis the default state of FW LLDP agent after POR, this change introduces\nmore reliable method for checking if agent is enabled.\n\nCurrent state of FW LLDP agent may be different if user disabled the\nagent, so i40e_get_fw_lldp_status() uses LLDP MIB checking to determine\nstatus of the agent.\n\nSigned-off-by: Piotr
