STRUCT MXL862XX_EXTENDEDVLAN_ALLOC(9)

💖 struct mxl862xx_extendedvlan_alloc(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — yes this is a real page from the kernel docs and yes we're gonna read it together, it's giving "study date but make it cute" 🎀

---

🌸 NAME 🌸

struct mxl862xx_extendedvlan_alloc — Extended VLAN block allocation. that's it, that's the whole gig 💅 it's the little struct that handles grabbing and releasing a whole block of extended VLANs.

---

✨ SYNOPSIS ✨

struct mxl862xx_extendedvlan_alloc {
    __le16 number_of_entries;
    __le16 extended_vlan_block_id;
 };

look at her. two fields. tiny. iconic. 👑

---

🦋 Members 🦋

• number_of_entries — Number of entries to allocate (input) / allocated (output). so on the way in you're like "hey firmware, may i have this many pls" and on the way out it tells you how many you actually got 🫶
• extended_vlan_block_id — Block ID assigned by firmware (output on alloc, input on free). firmware hands you this on alloc; you hand it back on free. it's a two-way street, no cap 🌈

---

💜 Description 💜

Used with MXL862XX_EXTENDEDVLAN_ALLOC and MXL862XX_EXTENDEDVLAN_FREE. literally those two commands, that's the whole vibe check. one to get the block, one to give it back 🧚
