UNION IWL_WOWLAN_PATTERN_DATA(9)

💖 NAME 💖

okay so welcome to union iwl_wowlan_pattern_data(9) — from the Kernel API Manual, bestie — and it's literally just Data for the different pattern types ✨

---

🎀 SYNOPSIS 🎀

The way this union is shaped, no cap:

union iwl_wowlan_pattern_data {
    struct iwl_wowlan_pattern_v1 bitmask;
    struct iwl_wowlan_ipv4_tcp_syn ipv4_tcp_syn;
    struct iwl_wowlan_ipv6_tcp_syn ipv6_tcp_syn;
 };

---

🌸 MEMBERS 🌸

• bitmask — the bitmask pattern data 🫶 like, that's its whole thing
• ipv4_tcp_syn — the IPv4 TCP SYN pattern data 💅 v4 girlie
• ipv6_tcp_syn — the IPv6 TCP SYN pattern data 🌈 v6 girlie, she's serving too

---

🦋 DESCRIPTION 🦋

So here's the tea 🔥: if you're gonna use wildcard addresses/ports, it's totally fine to just leave the union undefined. Like, don't fill it in, don't stress about it — undefined is the vibe check it needs to pass. Periodt.

not me emphasizing this — but fr fr, "leave it undefined" is the actual instruction, don't come for me 💀
