STRUCT IWL_SAP_ETH_FILTER(9)

💖 struct iwl_sap_eth_filter — a L2 filter 💖

okay so bestie, we're in the kernel API manual (Kernel API Manual, section 9, if we're being precise 👑) and today's main character is struct iwl_sap_eth_filter. It's a L2 filter. That's it, that's the whole vibe. Small struct, big energy. 💅

---

✨ SYNOPSIS ✨

like, here's literally the whole thing:

struct iwl_sap_eth_filter {
    u8 mac_address[6];
    u8 flags;
 };

not me being obsessed with how tidy this is 🎀 two members. two. no bloat, no drama, just a struct living its truth.

---

🌸 Members 🌸

• mac_address — the address to filter. it's a u8[6], so yes, six bytes, exactly like a MAC address should be. slay. 🦋
• flags — go check enum iwl_sap_eth_filter_flags for what these mean, bestie. iykyk. 🔥

lowkey a little aside: this struct is exactly as small as it looks, so don't go looking for hidden members. what you see is what you get, bestie. 🫶

and that's the page!! 💖 the source path got a lil truncated upstream as ./drivers/net/wireless/intel/i..., the date on it is October 2026, and it's all hanging out in struct iwl_sap_eth_filter(9). mwah, go filter some L2, ily, bye 🎀🌈⭐
