STRUCT BRCMF_PROTO_BCDC_HEADER(9)

💖 struct brcmf_proto_bcdc_header — BCDC header format 💖

okay so bestie, welcome to the Kernel API Manual ✨ this little page is all about struct brcmf_proto_bcdc_header, and ngl it's giving "small but iconic" — four tiny u8 fields doing the absolute most. it's literally the header format that sits in front of your packet data and tells everyone what's up 🎀

✨ NAME ✨

struct brcmf_proto_bcdc_header — the BCDC header format, periodt. 💅

🌸 SYNOPSIS 🌸

struct brcmf_proto_bcdc_header {
    u8 flags;
    u8 priority;
    u8 flags2;
    u8 data_offset;
 };

look at her. four bytes. main character energy fr fr 🦋

👑 Members 👑

• flags — this one's carrying the protocol and checksum info, iykyk. she knows things. 💜
• priority — 802.1d priority plus USB flow control info, and the flow control bits live in bit 4:7 specifically. yes bestie, they really said bit 4:7. 🫶
• flags2 — extra flags, and these ones are holding the dongle interface index. lowkey important. ✨
• data_offset — tells you where the packet data actually starts. and heads up: the header is followed by firmware signals. that's just how it is. 🌈

not me reading "header is following by firmware signals" and just nodding — that's the original wording, we keep the facts exactly as they are, no cap 💀
