STRUCT BRCMF_MF_PARAMS_LE(9)

💅 struct brcmf_mf_params_le(9)

okay so bestie, welcome to the Kernel API Manual ✨ — we're talking about struct brcmf_mf_params_le, which is literally the management frame parameters for the mgmt_frame iovar. yes, that's a mouthful, no cap. let's get into it 🎀

🌸 SYNOPSIS

struct brcmf_mf_params_le {
    __le32 version;
    __le32 dwell_time;
    __le16 len;
    __le16 frame_control;
    __le16 channel;
    u8 da[ETH_ALEN];
    u8 bssid[ETH_ALEN];
    __le32 packet_id;
    u8 data[];
};

look at that struct. it's giving "organized" and we're obsessed 🫶 copy it exactly, don't touch a single character, iykyk.

✨ DESCRIPTION — the Members, one by one

each of these little fields is a main character in its own right, so let's give them their moment 💖

• version — version of the iovar 🌈
• dwell_time — dwell duration in ms ⏱️
• len — length of frame data 📏
• frame_control — frame control, literally what it sounds like 💅
• channel — channel 📡
• da — peer MAC address 🦋
• bssid — BSS network identifier 👑
• packet_id — packet identifier 🎀
• data — frame data 🌸 (it's a flexible array, so it just keeps going, periodt)

ngl, data[] being a u8 array with no size is the flexible-array-member moment of the century — it lives at the end of the struct and just vibes 💀
