STRUCT NFP_FL_TUNNEL_OFFLOADS(9)

💖 NAME 💖

struct nfp_fl_tunnel_offloads — the priv data for tunnel offloads, bestie. That's literally the whole vibe.

So this is a page from the Kernel API Manual, and it's giving very much "kernel struct documentation but make it make sense." Let's get into it 🫶

---

✨ SYNOPSIS ✨

struct nfp_fl_tunnel_offloads {
    struct rhashtable offloaded_macs;
    struct list_head ipv4_off_list;
    struct list_head ipv6_off_list;
    struct mutex ipv4_off_lock;
    struct mutex ipv6_off_lock;
    struct ida mac_off_ids;
    struct notifier_block neigh_nb;
 };

That's the whole struct, no cap. Every member, exactly as it appears 👑

🎀 MEMBERS 🎀

Okay so here's the cast of characters, and each one has main character energy in its own little way:

• offloaded_macs — a hashtable holding the offloaded MAC addresses. It's the rhashtable of the group chat, fr fr 💅
• ipv4_off_list — a list of the IPv4 addresses that need to be offloaded. Keeping track, lowkey iconic ✨
• ipv6_off_list — same deal but for IPv6, a list of IPv6 addresses to offload. IPv6 gets its own list, we love equality 🌈
• ipv4_off_lock — the lock guarding the IPv4 address list. Do not touch the list without it, bestie 🔒
• ipv6_off_lock — the lock for the IPv6 address list. Same energy, different address family 💜
• mac_off_ids — an IDA used to manage id assignment for offloaded MACs. It's handing out IDs like a bouncer at the club 🎟️
• neigh_nb — a notifier block that monitors neighbour state. It's literally watching the neighbours, nosy but useful 🙈

That's the whole page, no skips, no shortcuts — every member and every reference is right there where it belongs 💖

Okay bye bestie, go off and read the kernel source, you got this 🦋

— signed off with love from ./drivers/net/ethernet/netrono..., dated October 2026, and yes the page is still called struct nfp_...nel_offloads(9) in the header because truncation is the moment 💀✨ 🎀
