STRUCT IWL_PROTO_OFFLOAD_CMD_V2(9)

🦋 struct iwl_proto_offload_cmd_v2(9) 🦋

okay so bestie, welcome to the Kernel API Manual, section 9 💅. We're talking about struct iwl_proto_offload_cmd_v2 — that's the ARP/NS offload configuration situation. Yes, version two. There's a v1, there's a v3, and there's this one. Slay.

✨ NAME ✨

struct iwl_proto_offload_cmd_v2 — ARP/NS offload configuration 🫶

Like, your NIC wants to keep answering for you while the rest of your machine is asleep. That's the whole vibe. It's giving "main character energy while the CPU naps" 😴👑

---

🌸 SYNOPSIS 🌸

struct iwl_proto_offload_cmd_v2 {
    struct iwl_proto_offload_cmd_common common;
    u8 remote_ipv6_addr[16];
    u8 solicited_node_ipv6_addr[16];
    u8 target_ipv6_addr[IWL_PROTO_OFFLOAD_NUM_IPV6_ADDRS_V2][16];
    u8 ndp_mac_addr[ETH_ALEN];
    u8 num_valid_ipv6_addrs;
    u8 reserved2[3];
 };

literally the whole struct. no cap, that's all of it. Notice how there's so many u8 [16] arrays — that's because IPv6 addresses are 16 bytes each, bestie. Sixteen. Every time. Obsessed with consistency tbh ✨

🎀 Members 🎀

okay let's go through them one by one, no skipping, I would never 🙈

• common — the common/IPv4 configuration 🧚. It's a struct iwl_proto_offload_cmd_common and yes there is a whole other manpage for it, see below.
• remote_ipv6_addr — the remote address to answer to (or zero if all) 💖. Like, if you leave it as zero it's answering to everyone. Very generous of it.
• solicited_node_ipv6_addr — broken 💀 — the manpage literally calls it broken. There's a solicited node address for each target address, so this single field can't actually represent that. It's not you, bestie, it's the struct. Not me defending a broken field but like... 🙈
• target_ipv6_addr — our target addresses 👑. It's the big one: u8 target_ipv6_addr[IWL_PROTO_OFFLOAD_NUM_IPV6_ADDRS_V2][16] — a whole little grid of addresses.
• ndp_mac_addr — neighbor solicitation response MAC address 🦋. This is the MAC that gets booped back at whoever's asking.
• num_valid_ipv6_addrs — the number of valid IPv6 addresses ⭐. Please keep it honest, it's how anyone knows how much of that address grid is real.
• reserved2 — reserved 🎀. Do not touch. It is not for you. It's reserved. Hands off. (u8 reserved2[3] — three whole bytes of "leave me alone".)

okay that's the whole page!! before you go — credit where it's due: this one comes from ./drivers/net/wireless/intel/i... and it's dated October 2026 🍓, and it's filed under struct iwl_...fload_cmd_v2(9) in the Kernel API Manual. mwah, go read the v3 ones next, they're longer 💋✨
