STRUCT IWL_NPCA_PARAMS(9)

💖 struct iwl_npca_params(9) 💖

okay bestie, buckle up — this is a page from the Kernel API Manual, section 9, and it's all about struct iwl_npca_params, the little struct that holds your NPCA parameters (that's non-primary channel access, iykyk ✨).

🌸 NAME 🌸

struct iwl_npca_params — NPCA parameters (non-primary channel access). literally the whole vibe of this struct in one line, no cap 🫶

✨ SYNOPSIS ✨

struct iwl_npca_params {
    __le16 dis_subch_bmap;
    u8 switch_delay;
    u8 switch_back_delay;
    u8 initial_qsrc;
    u8 min_dur_threshold;
    u8 flags;
    u8 reserved;
 };

look at her. seven fields. main character energy 👑 every single one copied exactly, don't come for me 💅

💅 Members 💅

• dis_subch_bmap — the disabled subchannel bitmap for NPCA. which subchannels are sitting this one out 🙈
• switch_delay — after the switch, delay TX according to the destination AP. like, wait your turn before you start transmitting, bestie ⏳
• switch_back_delay — switch back to the control channel before the OBSS frame end. yes, before — timing matters, don't be late 🕐
• initial_qsrc — indicates the value that's used to initialize the EDCAF QSRC[AC] variables. that's it, that's the whole job 🎀
• min_dur_threshold — the minimum PPDU time needed to switch to the non-primary NPCA channel (spec representation). too short? no switch for you 💀
• flags — the NPCA flags, see enum iwl_npca_flags. go look at the enum, it's got the real gossip 👀
• reserved — reserved for alignment purposes. she's just here for the vibes, padding things out so everything lines up 🧚
