STRUCT VIRTCHNL2_EVENT(9)

💖 struct virtchnl2_event(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — we're doing a whole deep-dive on struct virtchnl2_event and honestly? it's giving "tiny struct, big responsibilities." buckle up 🎀

---

🌸 NAME 🌸

struct virtchnl2_event — Event info. that's it, that's the vibe. 💅

---

✨ SYNOPSIS ✨

struct virtchnl2_event {
    __le32 event;
    __le32 link_speed;
    __le32 vport_id;
    u8 link_status;
    u8 pad;
    __le16 reserved;
 };

look at her. six fields, zero notes, absolute icon behavior 👑 (yes there's a stray space before that closing brace in the original and no, we do not fix it, we respect the source 💀).

---

🦋 Members 🦋

oke so let's go member by member, no skipping, we're doing this properly 🫶

• event — the event opcode. like, which event is this? check out enum virtchnl2_event_codes for the full menu 🍓
• link_speed — the link speed, handed to you in Mbps. yes Mbps, write it down 🔥
• vport_id — the Vport ID. literally what it says 💜
• link_status — the link status. the vibe check of the physical link, if you will ✨
• pad — padding. it's just sitting there being padding, we love a supporting character 🙈
• reserved — reserved. do not get creative with it, bestie, hands off 😭

---

🌈 Description 🌈

so here's the lore: the CP sends this message to inform the PF/VF driver of events that may affect it. that's the whole point of her existence 💅

and the best part? No direct response is expected from the driver — she's not waiting on a reply text, she's just letting you know 👑 though the driver may generate other messages in response to this one, so like… read the room, y'know? 👀

this whole thing is Associated with VIRTCHNL2_OP_EVENT. periodt. 🔥

ngl this is a notification, not a conversation — don't go sending a response back and making it weird 💀
