STRUCT VIRTCHNL2_MAC_ADDR_LIST(9)

🦋 struct virtchnl2_mac_addr_list(9) 🦋

okay so bestie, welcome to the Kernel API Manual — yes it's a real manual, yes it's giving ✨documentation✨, and yes we're gonna get through it together. This one's about a lil struct that carries a whole list of MAC addresses around. Cute, right? Let's go 💅

---

🌸 NAME 🌸

struct virtchnl2_mac_addr_list — literally just a list of MAC addresses, no cap 🎀

---

✨ SYNOPSIS ✨

struct virtchnl2_mac_addr_list {
    __le32 vport_id;
    __le16 num_mac_addr;
    u8 pad[2];
    struct virtchnl2_mac_addr mac_addr_list[];
 };

bestie look at that last field — it's a flexible array member, she's got main character energy and no fixed size 👑

---

💖 Members 💖

• vport_id — the vport id. which vport? that vport. the one this list belongs to 🫶
• num_mac_addr — the number of MAC addresses chillin' in the list. the count, the headcount, the vibe check total 🌈
• pad — padding. it's just there for alignment reasons, doing absolutely nothing and thriving 😌
• mac_addr_list — the actual list, with all the MAC address info inside it. this is the icon, the moment, the reason we're all here 💅

---

🔥 Description 🔥

so the PF/VF driver uses this struct to send a list of MAC addresses — the ones to be added or deleted — over to the CP. and then the CP does the actual action and sends back the status. teamwork, fr fr 🤝✨

it's associated with VIRTCHNL2_OP_ADD_MAC_ADDR and VIRTCHNL2_OP_DEL_MAC_ADDR, so if you see those two ops, just know this struct isn't far behind 👀
