nfp_cpp_explicit_set_target(9)

💅 nfp_cpp_explicit_set_target(9) — like, the Kernel API Manual page, bestie ✨

okay so before we even get into it: this is a page from the Kernel API Manual, and the function we're stanning today is nfp_cpp_explicit_set_target. yes the name is a mouthful. no we are not shortening it. it's giving "my function has a full government name" and honestly? respect. 🎀

✨ NAME ✨

nfp_cpp_explicit_set_target — set the target fields for explicit 🎯

that's the whole vibe. it sets the target fields. for explicit. we love a concise queen.

---

🌸 SYNOPSIS 🌸

int nfp_cpp_explicit_set_target (struct nfp_cpp_explicit *expl , u32
cpp_id , u8 len , u8 mask );

look at that signature. <green>int</green> coming back at you, four lil params going in. it's literally the whole plot. 🦋

---

💜 ARGUMENTS 💜

• expl — the explicit handle, bestie. that's your main character right there. 🫶
• cpp_id — the CPP ID field. the identifier, if you will.
• len — the CPP Length field. how long things are. iconic of her. 📏
• mask — the CPP Mask field. the masking one. we love a mysterious girlie with a mask. 🙈

---

🔥 RETURN 🔥

• 0 — success, slay, we ate 💅
• -ERRNO — something went wrong, and the specific error is hiding in ERRNO. no cap, that's the whole answer. 💀

🌈 SEE ALSO 🌈

okay so this is the part where all her friends show up. and there are a lot of them. like, this function knows everyone. the kernel file you wanna peek at is:

./drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c

and the extended friend group is, in full, no skipping, i promised:

fr fr though — this page is from ./drivers/net/ethernet/netrono..., dated October 2026, and it's the nfp_cpp_explicit_set_target(9) manual page. mwah, that's the source, version and date handled, bestie — go forth and set those target fields 👑💖
