STRUCT VIRTCHNL2_SINGLEQ_RX_BUF_DESC(9)

💅 STRUCT VIRTCHNL2_SINGLEQ_RX_BUF_DESC(9) 💅

okay so we're in the Kernel API Manual bestie, and today's main character is a struct. yes a whole struct. and honestly? she's kind of iconic in a quiet-luxury way 🎀

---

✨ NAME ✨

struct virtchnl2_singleq_rx_buf_desc — the SingleQ RX buffer descriptor format. that's it. that's her whole job. 💖

---

🌸 SYNOPSIS 🌸

struct virtchnl2_singleq_rx_buf_desc {
    __le64 pkt_addr;
    __le64 hdr_addr;
    __le64 rsvd1;
    __le64 rsvd2;
 };

look at that layout. four __le64 fields, all lined up, no drama, no cap ✨

---

🦋 MEMBERS 🦋

• pkt_addr — the packet buffer address. this is where your actual packet data lives, slay 💅
• hdr_addr — the header buffer address. the header hangs out here, separate from the packet body, iykyk
• rsvd1 — reserved. like, reserved-reserved. don't touch, she's not for you 🙈
• rsvd2 — also reserved. a second one. because one reserved field was lowkey not enough 🫶

⭐ DESCRIPTION ⭐

bestie, it's a SingleQ buffer layout and it looks exactly like this:

SingleQ buffer |
0| ---------------------------------------------------------------- | Rx
packet buffer address                                     |
---------------------------------------------------------------- | Rx
header buffer address                                     |
---------------------------------------------------------------- | RSV
| ---------------------------------------------------------------- | RSV
| ---------------------------------------------------------------- |
0|

so you got your Rx packet buffer address, then your Rx header buffer address, then two RSV slots that are just vibing doing absolutely nothing. the way the structure just... holds space for them 💀 reserved fields have main character energy for no reason fr fr.
