-    * Include LLDP support in base Layer2 and Layer3 classes. Due to the
-      widespread adoption of LLDP, this should improve mapping networks
-      when devices aren't supported in a more specific class.
     * Support obtaining FDB in Avaya SPBM edge deployments in L2::Baystack
       NOTE: This requires a RAPID-CITY MIB with the rcBridgeSpbmMacTable
     * Support for Fortinet devices in new class L3::Fortinet

     * No longer ignore interfaces based on name, in base L2/L3/L7 device
       classes. For several device classes SNMP::Info will now return tunnel
       interfaces and/or loopbacks, if present.
