ENUM IWL_MVM_RX_STATUS(9)

💅 enum iwl_mvm_rx_status — from the Kernel API Manual, bestie ✨

okay so. this is a page straight out of the Kernel API Manual, and it's all about enum iwl_mvm_rx_status — the little status blob the firmware writes for literally every single Rx packet 🎀. no cap, every one.

---

🌸 NAME 🌸

enum iwl_mvm_rx_status — written by fw for each Rx packet

like, the firmware itself hands you this on a platter for every packet it receives. iconic behavior honestly 🫶

✨ SYNOPSIS ✨

enum iwl_mvm_rx_status {
    RX_MPDU_RES_STATUS_CRC_OK ,

    RX_MDPU_RES_STATUS_STA_ID_SHIFT ,
    RX_MPDU_RES_STATUS_STA_ID_MSK

};

that's the whole roster 💖 (yes, the blank line before the closing brace stays, it's part of the vibe now)

🦋 Constants 🦋

okay bestie, one by one, no skipping, we're doing all of them 👑

• RX_MPDU_RES_STATUS_CRC_OK — the CRC is fine, we love to see it 💚
• RX_MPDU_RES_STATUS_OVERRUN_OK — there was no RXE overflow. no overflow, no drama ✨
• RX_MPDU_RES_STATUS_SRC_STA_FOUND — the station was found. she's here, she's accounted for 🎀
• RX_MPDU_RES_STATUS_KEY_VALID — the key was valid 🔑
• RX_MPDU_RES_STATUS_ICV_OK — the ICV is fine. and if it's not fine? the packet is destroyed. 💀 gone. say bye.
• RX_MPDU_RES_STATUS_MIC_OK — used for CCM alg only. the TKIP MIC is checked in the driver, not here, so don't come for this flag about it 🙈
• RX_MPDU_RES_STATUS_TTAK_OK — the TTAK is fine ✅
• RX_MPDU_RES_STATUS_MNG_FRAME_REPLAY_ERR — valid for alg = CCM_CMAC or alg = CCM only. it checks for replay attacks on 11w frames 🛡️
• RX_MPDU_RES_STATUS_SEC_NO_ENC — this frame is not encrypted. out here living free 🌈
• RX_MPDU_RES_STATUS_SEC_WEP_ENC — this frame is encrypted using WEP
• RX_MPDU_RES_STATUS_SEC_CCM_ENC — this frame is encrypted using CCM
• RX_MPDU_RES_STATUS_SEC_TKIP_ENC — this frame is encrypted using TKIP
• RX_MPDU_RES_STATUS_SEC_EXT_ENC — this frame is encrypted using extension algorithm
• RX_MPDU_RES_STATUS_SEC_CMAC_GMAC_ENC — this frame is protected using CMAC or GMAC 🔐
• RX_MPDU_RES_STATUS_SEC_ENC_ERR — this frame couldn't be decrypted 😭 it tried its best
• RX_MPDU_RES_STATUS_SEC_ENC_MSK — the bitmask of the encryption algorithm 🎭
• RX_MPDU_RES_STATUS_DEC_DONE — this frame has been successfully decrypted. slay 💅
• RX_MPDU_RES_STATUS_CSUM_DONE — the checksum was done by the hw 🖥️
• RX_MPDU_RES_STATUS_CSUM_OK — the checksum found no errors ✨
• RX_MDPU_RES_STATUS_STA_ID_SHIFT — station ID bit shift
• RX_MPDU_RES_STATUS_STA_ID_MSK — station ID mask

and that's the whole page bestie, nothing cut, nothing skipped, every single constant accounted for 💖

okay and for the cute sign-off: this one came from ./drivers/net/wireless/intel/i... and it's dated October 2026, filed under enum iwl_mvm_rx_status(9). that's a wrap, mwah 😘🌸
