STRUCT VIRTCHNL2_PTYPE(9)

💖 struct virtchnl2_ptype(9) 💖

okay bestie, welcome to the Kernel API Manual page for struct virtchnl2_ptype(9) — it’s giving packet type info, and we’re gonna read it together like the main characters we are. 💅

✨ NAME ✨

struct virtchnl2_ptype — Packet type info. periodt.

🦋 SYNOPSIS 🦋

       struct virtchnl2_ptype {
           __le16 ptype_id_10;
           u8 ptype_id_8;
           u8 proto_id_count;
           __le16 pad;
           __le16 proto_id[];
        };

🧩 Members 🧩

• ptype_id_10 — the 10-bit packet type, okay? that’s literally what it is.
• ptype_id_8 — the 8-bit packet type. slay.
• proto_id_count — number of protocol ids the packet supports; maximum of 32 protocol ids are supported. no cap.
• pad — padding. literally just padding, bestie.
• proto_id — proto_id_count decides the allocation of protocol id array. see enum virtchnl2_proto_hdr_type. iykyk.

🌸 Description 🌸

okay so based on the descriptor type the PF supports, CP fills ptype_id_10 or ptype_id_8 for flex and base descriptor respectively. that’s the whole vibe.

and if ptype_id_10 value is set to 0xFFFF, PF should consider this ptype as a dummy one and it is the last ptype. so like, that’s the end of the ptype list, bestie. 💀
