STRUCT VIRTCHNL2_SPLITQ_RX_BUF_DESC(9)

🎀 NAME 🎀

hey bestie, welcome to the Kernel API Manual page for struct virtchnl2_splitq_rx_buf_desc 🫶. In the running header it shows up as struct virt..._rx_buf_desc(9) — yes, the ellipsis is doing main character energy. It’s the SplitQ RX buffer descriptor format, no cap ✨.

🦋 SYNOPSIS 🦋

okay so this is the literal struct, and I mean literally literally:

       struct virtchnl2_splitq_rx_buf_desc {
           struct {
             __le16 buf_id;
             __le16 rsvd0;
             __le32 rsvd1;
           } qword0;
           __le64 pkt_addr;
           __le64 hdr_addr;
           __le64 rsvd2;
        };

• qword0 — RX buffer struct. the nested-struct moment, we love to see it.
  • qword0.buf_id — Buffer identifier.
  • qword0.rsvd0 — Reserved.
  • qword0.rsvd1 — Reserved.
• pkt_addr — Packet buffer address.
• hdr_addr — Header buffer address.
• rsvd2 — Rerserved. not my typo, bestie — that is literally the spelling in the source, and I am not fixing it 💅

🌈 Description 🌈

The source describes it as Receive Descriptors SplitQ buffer, and then gives this exact layout sketch. Pipes, 16, 0, all of it — preserved, untouched, iconic:

       Receive Descriptors SplitQ buffer |
       16|                   0|
       ---------------------------------------------------------------- | RSV
       | Buffer ID          |
       ---------------------------------------------------------------- | Rx
       packet buffer address                                     |
       ---------------------------------------------------------------- | Rx
       header buffer address                                     |
