ENUM IWL_TX_FLAGS(9)

💖 enum iwl_tx_flags(9) 💖

okay bestie, welcome to this Kernel API Manual page for enum iwl_tx_flags(9) — it's giving “bitmask lore” and honestly it ate. This is all about the bitmasks for tx_flags in the TX command. No cap, every constant matters here, so let's get into it ✨

🎀 Constants 🎀

bestie, here's the whole flag squad, one by one, with zero skips 💖

• TX_CMD_FLG_PROT_REQUIRE — use RTS or CTS-to-self to protect the frame.
• TX_CMD_FLG_WRITE_TX_POWER — update the current tx power value in the mgmt frame.
• TX_CMD_FLG_ACK — expect ACK from the receiving station.
• TX_CMD_FLG_STA_RATE — use the RS table with the initial index from the TX command. Otherwise, use rate_n_flags from the TX command.
• TX_CMD_FLG_BAR — this frame is a BA request, and an immediate BAR is expected. You must set TX_CMD_FLG_ACK with this flag.
• TX_CMD_FLG_TXOP_PROT — TXOP protection requested.
• TX_CMD_FLG_VHT_NDPA — mark frame is NDPA for VHT beamformer sequence.
• TX_CMD_FLG_HT_NDPA — mark frame is NDPA for HT beamformer sequence.
• TX_CMD_FLG_CSI_FDBK2HOST — mark to send feedback to host (only if good CRC).
• TX_CMD_FLG_BT_PRIO_POS — the position of the BT priority (bit 11 is ignored on old firmwares).
• TX_CMD_FLG_BT_PRIO_MASK — BT priority value.
• TX_CMD_FLG_BT_DIS — disable BT priority for this frame.
• TX_CMD_FLG_SEQ_CTL — set if FW should override the sequence control. Should be set for mgmt, non-QOS data, mcast, bcast and in scan command.
• TX_CMD_FLG_MORE_FRAG — this frame is non-last MPDU.
• TX_CMD_FLG_TSF — FW should calculate and insert TSF in the frame. Should be set for beacons and probe responses.
• TX_CMD_FLG_CALIB — activate PA TX power calibrations.
• TX_CMD_FLG_KEEP_SEQ_CTL — if seq_ctl is set, don't increase inner seq count.
• TX_CMD_FLG_MH_PAD — driver inserted 2 byte padding after MAC header. Should be set for 26/30 length MAC headers.
• TX_CMD_FLG_RESP_TO_DRV — zero this if the response should go only to FW.
• TX_CMD_FLG_TKIP_MIC_DONE — FW already performed TKIP MIC calculation.
• TX_CMD_FLG_DUR — disable duration overwriting used in PS-Poll Assoc-id.
• TX_CMD_FLG_FW_DROP — FW should mark frame to be dropped.
• TX_CMD_FLG_EXEC_PAPD — execute PAPD.
• TX_CMD_FLG_PAPD_TYPE — 0 for reference power, 1 for nominal power.
• TX_CMD_FLG_HCCA_CHUNK — mark start of TSPEC chunk.
