SPINEL_PROP_THREAD_LINK_METRICS_MGMT_ENH_ACK value

Link metrics Enhanced-ACK Based Probing management Format: 6Cd - Write only Required capability: `SPINEL_CAP_THREAD_LINK_METRICS` `6` : IPv6 destination address `C` : Indicate whether to register or clear the probing. `0` - clear, `1` - register `C` : List of requested metric ids encoded as bit fields in single byte +---------------+----+ | Metric | Id | +---------------+----+ | LQI | 1 | | Link margin | 2 | | RSSI | 3 | +---------------+----+ Result of configuration is reported asynchronously to the Host using the SPINEL_PROP_THREAD_LINK_METRICS_MGMT_RESPONSE. Whenever Enh-ACK IE report is received it is passed to the Host using the SPINEL_PROP_THREAD_LINK_METRICS_MGMT_ENH_ACK_IE property.
