ENUM IWL_SAP_IPV4_FILTER_FLAGS(9)

💅 enum iwl_sap_ipv4_filter_flags — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of this little kernel API page 💖 this is the enum iwl_sap_ipv4_filter_flags entry from the Kernel API Manual, and it's genuinely so cute and tidy. no cap.

---

🎀 NAME 🎀

enum iwl_sap_ipv4_filter_flags — this enum is the one used in &struct iwl_sap_ipv4_filter 🫶 like, that's its whole job, and it's serving.

---

✨ SYNOPSIS ✨

here's the whole squad in declaration order, no skips, no edits:

enum iwl_sap_ipv4_filter_flags {
    SAP_IPV4_FILTER_ICMP_PASS ,
    SAP_IPV4_FILTER_ICMP_COPY ,
    SAP_IPV4_FILTER_ARP_REQ_PASS ,
    SAP_IPV4_FILTER_ARP_REQ_COPY ,
    SAP_IPV4_FILTER_ARP_RESP_PASS ,
    SAP_IPV4_FILTER_ARP_RESP_COPY

};

periodt. six members, all accounted for 💅

🌸 Constants 🌸

every single one of these is a main character, so let's do them justice 💜

• SAP_IPV4_FILTER_ICMP_PASS — passes ICMP packets over to CSME 🦋
• SAP_IPV4_FILTER_ICMP_COPY — passes ICMP packets to the host 🌸
• SAP_IPV4_FILTER_ARP_REQ_PASS — passes ARP requests to CSME ✨
• SAP_IPV4_FILTER_ARP_REQ_COPY — passes ARP requests to the host 🎀
• SAP_IPV4_FILTER_ARP_RESP_PASS — passes ARP responses to CSME 🔥
• SAP_IPV4_FILTER_ARP_RESP_COPY — passes ARP responses to the host 👑

not me noticing the pattern… ICMP and ARP, each with a PASS and a COPY variant, and each destination stated plainly. it's giving structure. it's giving consistency. iykyk 😭

💡 quick vibe check: this page is literally just the enum definition plus its six constants — no options, no defaults, no exit statuses, no bugs section. sometimes a page is short and that's iconic. don't go looking for extra lore that isn't there 🙈
