STRUCT IWL_WOWLAN_IPV4_TCP_SYN(9)

💖 struct iwl_w...ipv4_tcp_syn(9) 💖

okay so this is a page straight out of the Kernel API Manual, and bestie, it's literally the blueprint for how your Wi-Fi card snoozes without missing a beat. we're talking WoWLAN energy, no cap. ✨

---

🌸 NAME 🌸

struct iwl_wowlan_ipv4_tcp_syn — the WoWLAN IPv4 TCP SYN pattern data. that's it, that's the whole vibe. it's the little packet-matching glow-up that lets your NIC spot a TCP SYN while the rest of the system is in full sleepy-girl mode 😴💅

---

🦋 SYNOPSIS 🦋

here's the shape of it, copy-pasted from the source of truth so nobody comes for me:

struct iwl_wowlan_ipv4_tcp_syn {
    u8 src_addr[IPV4_ADDR_SIZE];
    u8 dst_addr[IPV4_ADDR_SIZE];
    __le16 src_port;
    __le16 dst_port;
 };

look at that struct. four fields. tidy. iconic. main character energy fr fr. 🎀

---

✨ Members ✨

these are the squad. every single one matters, so let's give them their moment:

• src_addr — source IP address to match 🫶 the "who's calling" of the whole situation
• dst_addr — destination IP address to match 💌 the "who's getting called"
• src_port — source TCP port to match 🔥 little number, big job
• dst_port — destination TCP port to match 🍓 the port on the receiving end, periodt

that's literally the whole member list, nothing hidden, nothing extra. all four are required to make the pattern match work its magic. 🧚
