This is the implementation of Netlink notifications out of CFM. Notifications are initiated whenever a state change happens in CFM. IFLA_BRIDGE_CFM: Points to the CFM information. IFLA_BRIDGE_CFM_MEP_STATUS_INFO: This indicate that the MEP instance status are following. IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO: This indicate that the peer MEP status are following. CFM nested attribute has the following attributes in next level. IFLA_BRIDGE_CFM_MEP_STATUS_INSTANCE: The MEP instance number of the delivered status. The type is NLA_U32. IFLA_BRIDGE_CFM_MEP_STATUS_OPCODE_UNEXP_SEEN: The MEP instance received CFM PDU with unexpected Opcode. The type is NLA_U32 (bool). IFLA_BRIDGE_CFM_MEP_STATUS_VERSION_UNEXP_SEEN: The MEP instance received CFM PDU with unexpected version. The type is NLA_U32 (bool). IFLA_BRIDGE_CFM_MEP_STATUS_RX_LEVEL_LOW_SEEN: The MEP instance received CCM PDU with MD level lower than configured level. This frame is discarded. The type is NLA_U32 (bool). IFLA_BRIDGE_CFM_CC_PEER_STATUS_INSTANCE: The MEP instance number of the delivered status. The type is NLA_U32. IFLA_BRIDGE_CFM_CC_PEER_STATUS_PEER_MEPID: The added Peer MEP ID of the delivered status. The type is NLA_U32. IFLA_BRIDGE_CFM_CC_PEER_STATUS_CCM_DEFECT: The CCM defect status. The type is NLA_U32 (bool). True means no CCM frame is received for 3.25 intervals. IFLA_BRIDGE_CFM_CC_CONFIG_EXP_INTERVAL. IFLA_BRIDGE_CFM_CC_PEER_STATUS_RDI: The last received CCM PDU RDI. The type is NLA_U32 (bool). IFLA_BRIDGE_CFM_CC_PEER_STATUS_PORT_TLV_VALUE: The last received CCM PDU Port Status TLV value field. The type is NLA_U8. IFLA_BRIDGE_CFM_CC_PEER_STATUS_IF_TLV_VALUE: The last received CCM PDU Interface Status TLV value field. The type is NLA_U8. IFLA_BRIDGE_CFM_CC_PEER_STATUS_SEEN: A CCM frame has been received from Peer MEP. The type is NLA_U32 (bool). This is cleared after GETLINK IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO. IFLA_BRIDGE_CFM_CC_PEER_STATUS_TLV_SEEN: A CCM frame with TLV has been received from Peer MEP. The type is NLA_U32 (bool). This is cleared after GETLINK IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO. IFLA_BRIDGE_CFM_CC_PEER_STATUS_SEQ_UNEXP_SEEN: A CCM frame with unexpected sequence number has been received from Peer MEP. The type is NLA_U32 (bool). When a sequence number is not one higher than previously received then it is unexpected. This is cleared after GETLINK IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO.
