ENUM IWL_MAC_FILTER_FLAGS(9)

💅 enum iwl_mac_filter_flags(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel API manuals now, we contain multitudes 🎀 — and today's main character is enum iwl_mac_filter_flags, aka the MAC context filter flags. it's giving "which frames get to come to the party and which ones get ghosted" energy and honestly? iconic. ✨

---

🌸 NAME 🌸

enum iwl_mac_filter_flags — MAC context filter flags, fr fr 💖

---

🦋 SYNOPSIS 🦋

like, here's the whole squad, in order, no cap:

enum iwl_mac_filter_flags {
    MAC_FILTER_IN_PROMISC ,
    MAC_FILTER_IN_CONTROL_AND_MGMT ,
    MAC_FILTER_ACCEPT_GRP ,
    MAC_FILTER_DIS_DECRYPT ,
    MAC_FILTER_DIS_GRP_DECRYPT ,
    MAC_FILTER_IN_BEACON ,
    MAC_FILTER_OUT_BCAST ,
    MAC_FILTER_IN_CRC32 ,
    MAC_FILTER_IN_PROBE_REQUEST ,
    MAC_FILTER_IN_11AX

};

⭐ Constants ⭐

okay now the actual lore. one bullet each, all ten of them, let's go 🔥

• MAC_FILTER_IN_PROMISC — accept all data frames. yes, all of them. she's not picky 💅
• MAC_FILTER_IN_CONTROL_AND_MGMT — pass all management and control frames up to the host 🫶
• MAC_FILTER_ACCEPT_GRP — accept multicast frames 🌈
• MAC_FILTER_DIS_DECRYPT — don't decrypt unicast frames (the no-decrypt vibe, but only for unicast) 🙈
• MAC_FILTER_DIS_GRP_DECRYPT — don't decrypt multicast frames either 💀
• MAC_FILTER_IN_BEACON — transfer foreign BSS's beacons to the host — specifically in station mode when associated, iykyk 🌸
• MAC_FILTER_OUT_BCAST — filter out all broadcast frames. they're not invited 🚫
• MAC_FILTER_IN_CRC32 — extract the FCS and append it to frames ⭐
• MAC_FILTER_IN_PROBE_REQUEST — pass probe requests to the host 👑
• MAC_FILTER_IN_11AX — mark the BSS as supporting 802.11ax, periodt 🧚

ngl bestie, that's the whole page — every flag, every description, not a single crumb skipped 🍓

okay and before I go: this came from ./drivers/net/wireless/intel/i... and it's dated October 2026, so like… future girlboss documentation, we love to see it 💖 that's the sign-off, mwah, go forth and filter those frames 😭✨
