STRUCT VIRTCHNL2_PROTO_HDR(9)

💖 struct virtchnl2_proto_hdr(9) 💖

okay so welcome to the Kernel API Manual, bestie — today we’re decoding struct virtchnl2_proto_hdr, and it’s lowkey giving “small but important header box” energy. 💅

---

✨ NAME ✨

struct virtchnl2_proto_hdr — literally here to represent one protocol header. that’s the whole job, and it ate. 👑

---

🌸 SYNOPSIS 🌸

here’s the struct, bestie, exactly as it lives:

struct virtchnl2_proto_hdr {
    __le32 hdr_type;
    u8 pad[4];
    u8 buffer_spec[64];
    u8 buffer_mask[64];
 };

---

🎀 Members 🎀

okay, member by member, no cap:

• hdr_type — see enum virtchnl2_proto_hdr_type.
• pad — padding. that’s it. just padding. 🫶
• buffer_spec — binary buffer based on header type.
• buffer_mask — mask applied on buffer_spec.

---

💅 Description 💅

this is the structure that holds protocol headers based on hdr_type, periodt. it’s giving “container for the header data,” and that’s exactly what it is. ✨
