STRUCT NFP_TUN_NEIGH_V4(9)

💖 struct nfp_tun_neigh_v4(9) 💖

okay so bestie, listen — this is a page from the Kernel API Manual, and it's literally all about struct nfp_tun_neigh_v4, which is the neighbour/route entry on the NFP for IPv4. yes, the actual NFP. we're in the netronome flower driver now, hold my iced coffee 🧚

✨ NAME ✨

struct nfp_tun_neigh_v4 — the neighbour/route entry on the NFP for IPv4, and honestly? she's iconic for it 👑

---

🌸 SYNOPSIS 🌸

the whole struct, laid out, no cap:

struct nfp_tun_neigh_v4 {
    __be32 dst_ipv4;
    __be32 src_ipv4;
    struct nfp_tun_neigh common;
    struct nfp_tun_neigh_ext ext;
    struct nfp_tun_neigh_lag lag;
 };

like five fields, each one doing its little job. she ate 💅

🎀 Members 🎀

okay so here's the field-by-field vibe check, keep up:

• dst_ipv4 — the destination IPv4 address 🎯 like where we're headed, fr fr
• src_ipv4 — the source IPv4 address 🏁 where it came from, the origin story
• common — the neighbour/route common info 🌈 the shared, everyday stuff
• ext — the neighbour/route extended info ✨ the extra details, the bonus round
• lag — the lag port info 🔗 port info for the lag, periodt

lowkey a whole struct family reunion in here and you're invited 🫶

and that's the page, bestie!! 💜 this cutie came from ./drivers/net/ethernet/netrono... (the source path is truncated in the original, so I'm keeping it exactly as it was handed to me, don't come for me 😭) and it's dated October 2026 — so yeah, future vibes, she's ahead of her time ⭐ bye bestie, go read the other structs, mwah 🎀
