Control block structure used to hold metadata for the payload passed in sl_wifi_send_transceiver_data.
Contains control flags and other metadata for the payload. The control flags specify various options for the packet, such as whether it is a 4-address packet, a QoS packet, or if a fixed data rate should be used.

Control flags bit description:
Reserved.
Reserved.
Data Packets are queued to respective queue based on priority. Best Effort - 0, Background - 1, Video - 2, Voice - 3.
Rates shall be provided as per sl_wifi_data_rate_t. Only 11b/g rates shall be supported.
Used for synchronization between data packets sent and reports received. Application shall provide token/identifier per PPDU. MAC layer shall send the same token/identifier in status report along with the status of the transmitted packet.
Receiver MAC address.
Transmitter MAC address.
Destination MAC address.
Source MAC address. Initialization of addr4 is optional.

ctrl_flags#
uint8_t sl_wifi_transceiver_tx_data_control_t::ctrl_flags
Control flags bit description:
Bit position | ctrl_flags bit description |
|---|---|
0 | Shall be set for 4-address packet or unset for 3-address packet. addr4 is ignored if set to 0. |
1 | Shall be set for QoS packet. QoS control field shall not be present in the MAC header for non-QoS packet. priority is ignored if set to 0. |
2 | Shall be set to use the fixed data rate provided in the rate field. If set to 0, rate field is ignored and auto rate shall be used. |
3 | Shall be set to enable ToDS bit in Frame Control. Valid only for 3-addr packet (bit 0 is unset). |
4 | Shall be set to enable FromDS bit in Frame Control. Valid only for 3-addr packet (bit 0 is unset). |
5 | Shall be set if host requires TX data status report. Token is used for synchronization between data packets sent and reports received. |
6:7 | Reserved. |
Note
If addr1 is multicast/broadcast, ctrl_flags bit 1 is ignored and the frame is sent as a non-QoS frame, i.e. QoS control field shall not be present in the MAC header.
