The Link Quality Indication data exposed by drivers could not be accessed from userspace. Since this data is per-datagram received, it makes sense to make it available to userspace application through the ancillary data mechanism in recvmsg rather than through ioctls. This can be activated using the socket option WPAN_WANTLQI under SOL_IEEE802154 protocol. This LQI data is available in the ancillary data buffer under the SOL_IEEE802154 level as the type WPAN_LQI. The value is an unsigned byte indicating the link quality with values ranging 0-255.
