+ * V18 to V19
+ * ----------
+ *      - Remove (struct iw_point *)->pointer from events and streams
+ *      - Remove header includes to help user space
+ *      - Increase IW_ENCODING_TOKEN_MAX from 32 to 64
+ *      - Add IW_QUAL_ALL_UPDATED and IW_QUAL_ALL_INVALID macros
+ *      - Add explicit flag to tell stats are in dBm : IW_QUAL_DBM
+ *      - Add IW_IOCTL_IDX() and IW_EVENT_IDX() macros
