STRUCT IWL_REG_CAPA(9)

💖 struct iwl_reg_capa(9) — the Kernel API Manual glow-up 💖

okay so bestie, welcome to struct iwl_reg_capa from the Kernel API Manual ✨ — this is the struct for global regulatory capabilities, and it's the main character for handling the different APIs of reg_capa_flags. no cap, it's literally the vibe check for what your regulatory domain is allowed to do 🦋

✨ SYNOPSIS ✨

struct iwl_reg_capa {
    bool allow_40mhz;
    bool allow_80mhz;
    bool allow_160mhz;
    bool allow_320mhz;
    bool disable_11ax;
    bool disable_11be;
    bool disable_11bn;
    enum iwl_puncturing_status puncturing_status;
 };

look at her. eight whole fields. iconic 💅

🌸 Members 🌸

• allow_40mhz — an 11n channel with a width of 40Mhz is allowed for this regulatory domain. slay 💖
• allow_80mhz — an 11ac channel with a width of 80Mhz is allowed for this regulatory domain (valid only in 5 and 6 Ghz). yep, 5 and 6 Ghz ONLY, don't get it twisted 🎀
• allow_160mhz — an 11ac channel with a width of 160Mhz is allowed for this regulatory domain (valid only in 5 and 6 Ghz). again — 5 and 6 Ghz only, queen 💅
• allow_320mhz — an 11be channel with a width of 320Mhz is allowed for this regulatory domain (valid only in 6 Ghz). 6 Ghz only bestie, that's the whole rule 🦋
• disable_11ax — 11ax is forbidden for this regulatory domain. forbidden fr fr 🙈
• disable_11be — 11be is forbidden for this regulatory domain. also forbidden, we don't make the rules 💀
• disable_11bn — UHR/11bn is not allowed for this regulatory domain. nope, not happening ✨
• puncturing_status — the EHT puncturing status for the current MCC. see enum iwl_puncturing_status. (iykyk 👑)

real talk: the allow_* booleans and the disable_* booleans are both just vibes for this regulatory domain — read each one exactly as written, no guessing 💜
