STRUCT BRCMF_PNO_PARAM_LE(9)

💅 struct brcmf_pno_param_le(9) — like, the PNO scan config tea ☕✨

okay so bestie, grab ur iced coffee 🍓 because we're diving into the Kernel API Manual and this one is literally called struct brcmf_pno_param_le — it's the struct that holds all the PNO scan configuration parameters 🎀. yes. that's the whole vibe. let's get into it 💖

✨ SYNOPSIS ✨

okay so here's the shape of it, and ngl it's giving "a lot of __le32s" but we love her anyway 🫶:

struct brcmf_pno_param_le {
    __le32 version;
    __le32 scan_freq;
    __le32 lost_network_timeout;
    __le16 flags;
    __le16 rssi_margin;
    u8 bestn;
    u8 mscan;
    u8 repeat;
    u8 exp;
    __le32 slow_freq;
 };

like, look at that little trailing }; with the extra space — iconic, no notes 💀

🌸 Members 🌸 (the cast, the main characters)

• version — the PNO parameters version. that's it, that's her job. keeping track of which version of the params we're looking at 👑
• scan_freq — the scan frequency. how often we're out here scanning, fr fr 🔥
• lost_network_timeout — measured in #sec., this is how long it takes before a discovered network gets declared as lost 😭 like sorry babe, we didn't see you in time, you're gone now 💔
• flags — a bit field that controls features of PFN, such as the sort criteria auto enable switch and background scan. it's the little switchboard of the whole operation, highkey powerful 🎛️✨
• rssi_margin — the margin that avoids jitter when choosing a PFN based on the RSSI sort criteria. she's the chill friend who stops everyone from flip-flopping every two seconds, we stan 🧚
• bestn — the number of best networks in each scan. the elite little lineup 👑💅
• mscan — the number of scans recorded. receipts. we keep them 📝
• repeat — the minimum number of scan intervals before the scan frequency changes in an adaptive scan. like, give it a minute before you switch up the whole strategy okay 🙈
• exp — exponent of 2 for the maximum scan interval. math babe 🧮✨
• slow_freq — the slow scan period. the slow girlie of the scan world, she takes her time 🌸🦋

real talk: notice how the file path got cut off in the footer as ./drivers/net/wireless/broadco... — that's just how it showed up, no cap, i'm not fixing it, that's the source's business 💀

and that's the whole page bestie!! 💖 this came from the Kernel API Manual, dated October 2026 🌈 — and the footer source path was, as mentioned, ./drivers/net/wireless/broadco... (truncated, rip ✂️). go forth and configure ur PNO scans, periodt 💅✨🦋
