bridge: cfm: Netlink SET configuration Interface.
This is the implementation of CFM netlink configuration set information interface. Add new nested netlink attributes. These attributes are used by the user space to create/delete/configure CFM instances. SETLINK: IFLA_BRIDGE_CFM: Indicate that the following attributes are CFM. IFLA_BRIDGE_CFM_MEP_CREATE: This indicate that a MEP instance must be created. IFLA_BRIDGE_CFM_MEP_DELETE: This indicate that a MEP instance must be deleted. IFLA_BRIDGE_CFM_MEP_CONFIG: This indicate that a MEP instance must be configured. IFLA_BRIDGE_CFM_CC_CONFIG: This indicate that a MEP instance Continuity Check (CC) functionality must be configured. IFLA_BRIDGE_CFM_CC_PEER_MEP_ADD: This indicate that a CC Peer MEP must be added. IFLA_BRIDGE_CFM_CC_PEER_MEP_REMOVE: This indicate that a CC Peer MEP must be removed. IFLA_BRIDGE_CFM_CC_CCM_TX: This indicate that the CC transmitted CCM PDU must be configured. IFLA_BRIDGE_CFM_CC_RDI: This indicate that the CC transmitted CCM PDU RDI must be configured. CFM nested attribute has the following attributes in next level. SETLINK RTEXT_FILTER_CFM_CONFIG: IFLA_BRIDGE_CFM_MEP_CREATE_INSTANCE: The created MEP instance number. The type is u32. IFLA_BRIDGE_CFM_MEP_CREATE_DOMAIN: The created MEP domain. The type is u32 (br_cfm_domain). It must be BR_CFM_PORT. This means that CFM frames are transmitted and received directly on the port - untagged. Not in a VLAN. IFLA_BRIDGE_CFM_MEP_CREATE_DIRECTION: The created MEP direction. The type is u32 (br_cfm_mep_direction). It must be BR_CFM_MEP_DIRECTION_DOWN. This means that CFM frames are transmitted and received on the port. Not in the bridge. IFLA_BRIDGE_CFM_MEP_CREATE_IFINDEX: The created MEP residence port ifindex. The type is u32 (ifindex). IFLA_BRIDGE_CFM_MEP_DELETE_INSTANCE: The deleted MEP instance number. The type is u32. IFLA_BRIDGE_CFM_MEP_CONFIG_INSTANCE: The configured MEP instance number. The type is u32. IFLA_BRIDGE_CFM_MEP_CONFIG_UNICAST_MAC: The configured MEP unicast MAC address. The type is 6*u8 (array). This is used as SMAC in all transmitted CFM frames. IFLA_BRIDGE_CFM_MEP_CONFIG_MDLEVEL: The configured MEP unicast MD level. The type is u32. It must be in the range 1-7. No CFM frames are passing through this MEP on lower levels. IFLA_BRIDGE_CFM_MEP_CONFIG_MEPID: The configured MEP ID. The type is u32. It must be in the range 0-0x1FFF. This MEP ID is inserted in any transmitted CCM frame. IFLA_BRIDGE_CFM_CC_CONFIG_INSTANCE: The configured MEP instance number. The type is u32. IFLA_BRIDGE_CFM_CC_CONFIG_ENABLE: The Continuity Check (CC) functionality is enabled or disabled. The type is u32 (bool). IFLA_BRIDGE_CFM_CC_CONFIG_EXP_INTERVAL: The CC expected receive interval of CCM frames. The type is u32 (br_cfm_ccm_interval). This is also the transmission interval of CCM frames when enabled. IFLA_BRIDGE_CFM_CC_CONFIG_EXP_MAID: The CC expected receive MAID in CCM frames. The type is CFM_MAID_LENGTH*u8. This is MAID is also inserted in transmitted CCM frames. IFLA_BRIDGE_CFM_CC_PEER_MEP_INSTANCE: The configured MEP instance number. The type is u32. IFLA_BRIDGE_CFM_CC_PEER_MEPID: The CC Peer MEP ID added. The type is u32. When a Peer MEP ID is added and CC is enabled it is expected to receive CCM frames from that Peer MEP. IFLA_BRIDGE_CFM_CC_RDI_INSTANCE: The configured MEP instance number. The type is u32. IFLA_BRIDGE_CFM_CC_RDI_RDI: The RDI that is inserted in transmitted CCM PDU. The type is u32 (bool). IFLA_BRIDGE_CFM_CC_CCM_TX_INSTANCE: The configured MEP instance number. The type is u32. IFLA_BRIDGE_CFM_CC_CCM_TX_DMAC: The transmitted CCM frame destination MAC address. The type is 6*u8 (array). This is used as DMAC in all transmitted CFM frames. IFLA_BRIDGE_CFM_CC_CCM_TX_SEQ_NO_UPDATE: The transmitted CCM frame update (increment) of sequence number is enabled or disabled. The type is u32 (bool). IFLA_BRIDGE_CFM_CC_CCM_TX_PERIOD: The period of time where CCM frame are transmitted. The type is u32. The time is given in seconds. SETLINK IFLA_BRIDGE_CFM_CC_CCM_TX must be done before timeout to keep transmission alive. When period is zero any ongoing CCM frame transmission will be stopped. IFLA_BRIDGE_CFM_CC_CCM_TX_IF_TLV: The transmitted CCM frame update with Interface Status TLV is enabled or disabled. The type is u32 (bool). IFLA_BRIDGE_CFM_CC_CCM_TX_IF_TLV_VALUE: The transmitted Interface Status TLV value field. The type is u8. IFLA_BRIDGE_CFM_CC_CCM_TX_PORT_TLV: The transmitted CCM frame update with Port Status TLV is enabled or disabled. The type is u32 (bool). IFLA_BRIDGE_CFM_CC_CCM_TX_PORT_TLV_VALUE: The transmitted Port Status TLV value field. The type is u8.
