NFP_CPP_INTERFACE_UNIT_of(9)

💅 NFP_CPP_INTERFACE_UNIT_of(9) 💅

okay bestie, this is a page from the Kernel API Manual — yes, the kernel, the big serious one — and it's about getting the interface unit out of an NFP Interface ID. tiny function, huge group-chat energy. let's go 🫶

---

✨ NAME ✨

NFP_CPP_INTERFACE_UNIT_of — get the interface unit 🌸

like, that's literally it. that's the whole job. she extracts one little field for you and she does it fabulously. 💅

---

🦋 SYNOPSIS 🦋

NFP_CPP_INTERFACE_UNIT_of (interface );

no cap, that's the whole call. one argument, in and out, main character energy. ✨

---

🎀 ARGUMENTS 🎀

• interface — the NFP Interface ID 💖 (yes queen, the ID itself, not a pointer to it, not a struct, the ID. we love a straightforward parameter.)

---

👑 RETURN 👑

the unit of that NFP Interface ID, periodt. ⭐

she gives you back the interface's unit and then she's done — no side quests, no hidden surprises, just the unit. iykyk 🧚

lowkey obsessed with how small this is. one job. one return value. iconic behavior fr fr.

🌈 SEE ALSO 🌈

okay this is the friend group, and they're all linked together, so let me introduce everyone 🎀:

• the kernel file ./drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cpp.h — the home base, the hangout spot 💜
• NFP_CPP_ID(9)
• NFP_CPP_ISLAND_ID(9)
• NFP_CPP_ID_TARGET_of(9)
• NFP_CPP_ID_TOKEN_of(9)
• NFP_CPP_ID_ACTION_of(9)
• NFP_CPP_ID_ISLAND_of(9)
• NFP_CPP_INTERFACE(9)
• NFP_CPP_INTERFACE_TYPE_of(9)
• NFP_CPP_INTERFACE_CHANNEL_of(9)
• nfp_cppcore_pcie_unit(9)
• struct nfp_cpp_operations(9)

all the _of girlies are literally the same vibe — they each pull a different field out of an ID. this one just happens to be the unit one. 💅

and that's the page!! go forth and get your interface units, bestie 💖

🌸 this one came from ./drivers/net/ethernet/netrono..., dated October 2026, and it's still filed under NFP_CPP_INTERFACE_UNIT_of(9) — mwah, bye! 💋🎀
