- * When calling CMD_802_11_SUBSCRIBE_EVENT with CMD_ACT_GET, me might

- * firmware. Here's an example:
- * 04 01 02 00 00 00 05 01 02 00 00 00 06 01 02 00
- * 00 00 07 01 02 00 3c 00 00 00 00 00 00 00 03 03
- * 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
- *
- * The 04 01 is the TLV type (here TLV_TYPE_RSSI_LOW), 02 00 is the length,
- * 00 00 are the data bytes of this TLV. For this TLV, their meaning is
- * defined in mrvlietypes_thresholds
- *
- * This function searches in this TLV data chunk for a given TLV type
- * and returns a pointer to the first data byte of the TLV, or to NULL
- * if the TLV hasn't been found.
