Control block structure used to hold meta data for the payload passed in sl_wifi_send_transceiver_data.

Public Attributes#

uint8_t
ctrl_flags
uint8_t
reserved1
uint8_t
reserved2
uint8_t
priority

Data Packets are queued to respective queue based on priority. Best Effort - 0, Background - 1, Video - 2, Voice - 3.

sl_wifi_data_rate_t
rate

Rates shall be provided as per sl_wifi_data_rate_t. Only 11b/g rates shall be supported.

uint32_t
token

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.

uint8_t
addr1

Receiver MAC address.

uint8_t
addr2

Transmitter MAC address.

uint8_t
addr3

Destination MAC address.

uint8_t
addr4

Source MAC address. Initialization of addr4 is optional.

Public Attribute Documentation#

ctrl_flags#

uint8_t sl_wifi_transceiver_tx_data_control_t::ctrl_flags

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.
