STRUCT VIRTCHNL2_GET_LAN_MEMORY_REGIONS(9)

✨ struct virtchnl2_get_lan_memory_regions(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a little struct with big "tell me where the memory lives" energy, and honestly? she ate.

---

🌸 NAME 🌸

struct virtchnl2_get_lan_memory_regions — literally just a list of LAN MMIO memory regions 🎀

---

🦋 SYNOPSIS 🦋

struct virtchnl2_get_lan_memory_regions {
    __le16 num_memory_regions;
    u8 pad[6];
    struct virtchnl2_mem_region mem_reg[];
 };

no cap, that's the whole shape of her 💅

---

👑 Members 👑

• num_memory_regions — the number of memory regions 🍓 like, how many are we talking
• pad — padding ✨ it's just vibes and empty space, don't think about it too hard
• mem_reg — the list with memory region info 🧚 this is the main character, the actual data right here

---

🌈 Description 🌈

so here's the tea: the PF/VF sends this message to find out which LAN MMIO memory regions it should map 🫶 that's it, that's the whole errand. it's giving "hey bestie, which regions am I supposed to map?" and the answer comes back in mem_reg. iconic. 🔥
