STRUCT BRCMF_EVENT_MSG(9)

💌 struct brcmf_event_msg(9) — the kernel API manual bestie

okay so this is struct brcmf_event_msg(9), and if you're here you're probably poking at brcmfmac firmware events and wondering what all these fields mean. don't stress — it's literally just a firmware event message, and we're gonna go through every single member together 🫶

✨ NAME ✨

struct brcmf_event_msg — firmware event message. that's it, that's the vibe. it's the lil' struct that carries the news when the firmware wants to tell you something 💅

---

🌸 SYNOPSIS 🌸

here's the whole glow-up, exactly as it lives in the header — no edits, no notes, copy-paste ready:

struct brcmf_event_msg {
    u16 version;
    u16 flags;
    u32 event_code;
    u32 status;
    u32 reason;
    s32 auth_type;
    u32 datalen;
    u8 addr[ETH_ALEN];
    char ifname[IFNAMSIZ];
    u8 ifidx;
    u8 bsscfgidx;
 };

🎀 Members 🎀

okay bestie, member-by-member, no skipping, we're doing the whole roster ⭐

• version — the version information. it's giving "hi, which version of me are you talking to" 🦋
• flags — the event flags. lil' bitty bits of extra context for the event 👑
• event_code — the firmware event code. this is the main character, the thing that tells you what happened 🔥
• status — status information. how'd it go? this knows 💀
• reason — the reason code. the "why tho" field, essential for the lore 🙈
• auth_type — the authentication type. yeah, that kind of auth 🌈
• datalen — the length of the event data buffer. so you know how much data you're working with, no guesses 💜
• addr — the ether address. ethernet address things, you know how it is 🍓
• ifname — the interface name. which interface is this event about, exactly 🧚
• ifidx — the interface index. the numeric bestie to ifname ✨
• bsscfgidx — the bsscfg index. yes it's a real field, yes you need it, yes it's iconic 💖

ngl there are a lot of fields here but every single one is pulling its weight. zero filler. periodt 💅
