Section 8 says:

                  container lacp {
                    if-feature "lacp";
                    leaf enabled {
                      type boolean;
                      default "false";
                      description
                        "LACP on/off.  By default, LACP is disabled.";
                    }
                    leaf mode {
                      type neg-mode;
                      description
                        "LACP mode.  LACP modes have active mode and
                         passive mode ('false').  'Active mode' means
                         initiating the auto-speed negotiation and
                         trying to form an Ethernet channel with the
                         other end.  'Passive mode' means not initiating
                         the negotiation but responding to LACP packets
                         initiated by the other end (e.g., full duplex
                         or half duplex).";
                    }

It should say:

                  container lacp {
                    if-feature "lacp";
                    leaf enabled {
                      type boolean;
                      default "false";
                      description
                        "LACP on/off.  By default, LACP is disabled.";
                    }
                    leaf mode {
                      type identityref {
                        base lacp-mode;
                      }
                      description
                        "LACP mode. LACP modes have active mode and
                         passive mode ('false').  'Active mode' means
                         initiating the auto-speed negotiation and
                         trying to form an Ethernet channel with the
                         other end.  'Passive mode' means not initiating
                         the negotiation but responding to LACP packets
                         initiated by the other end (e.g., full duplex
                         or half duplex).";
                    }


Also, make this change: 

OLD:

           |  +--rw lag-interfaces {lag-interface}?
           |  |  +--rw lag-interface* [index]
           |  |     +--rw index    string
           |  |     +--rw lacp {lacp}?
           |  |        +--rw enabled?           boolean
           |  |        +--rw mode?              neg-mode

NEW:

           |  +--rw lag-interfaces {lag-interface}?
           |  |  +--rw lag-interface* [index]
           |  |     +--rw index    string
           |  |     +--rw lacp {lacp}?
           |  |        +--rw enabled?           boolean
           |  |        +--rw mode?              identityref

Notes:

The LACP mode can be set to active or passive, which is not what neg-mode is supposed to cover. lacp-mode identity should be used, instead.

The errata looks valid, but given this requires a new revision of the YANG module a new RFC needs to be published.
