STRUCT TB_CAP_EXTENDED_SHORT(9)

💅 struct tb_cap_extended_short — Kernel API Manual ✨

🌸 NAME 🌸

struct tb_cap_extended_short — Switch extended short capability. Okay bestie, this is the page for that exact struct, and it’s giving kernel-register realness. 💖

🦋 SYNOPSIS 🦋

Here’s the whole struct layout, no cap — keep it character-for-character:

       struct tb_cap_extended_short {
           u8 next;
           u8 cap;
           u8 vsec_id;
           u8 length;
        };

🎀 Members 🎀

• next — Pointer to the next capability. If next and length are zero then we have a long cap. 👀 So yeah, that zero-zero combo is the long-cap signal.
• cap — Base capability ID (see enum tb_switch_cap). ✨
• vsec_id — Vendor specific capability ID (see enum switch_vse_cap). 🦋
• length — Length of this capability. 📏
