nfp_nfd3_tx_ring_alloc(9)

💖 nfp_nfd3_tx_ring_alloc(9) 💖

okay so bestie, welcome to the kernel API manual for nfp_nfd3_tx_ring_alloc(9) — yes that's the whole manual name, yes it's a mouthful, no we're not shortening it. this is the Netronome NFP gigabit ethernet driver corner of the kernel and we're about to allocate some TX ring resources together. grab a snack 🍓

---

✨ NAME ✨

nfp_nfd3_tx_ring_alloc — Allocate resource for a TX ring. that's it, that's the whole job. it allocates. for a TX ring. slay 💅

---

🌸 SYNOPSIS 🌸

int nfp_nfd3_tx_ring_alloc (struct nfp_net_dp *dp , struct
nfp_net_tx_ring *tx_ring );

literally just two args, both structs, both pointers, and it hands you back an int. no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

• dp — the NFP Net data path struct. this is the data path vibes, the whole context of what we're working with ✨
• tx_ring — the TX Ring structure to allocate. this is the ring we're about to give resources to — main character energy, honestly 👑

---

🎀 RETURN 🎀

• 0 on success — we ate, we slayed, the ring got its resources 💖
• negative errno otherwise — something went sideways, and the negative errno tells you what. not the cute outcome but at least it's informative 😭

---

🌈 SEE ALSO 🌈

• Kernel file ./drivers/net/ethernet/netronome/nfp/nfd3/rings.c — go read the source bestie, it's right there in the tree 📂
• nfp_nfd3_tx_ring_reset(9) — the reset one 🔄
• nfp_nfd3_tx_ring_free(9) — and the free one, because what goes alloc'd must eventually come free 💀

---

lowkey important: the man page source lives at ./drivers/net/ethernet/netrono... (yes it's truncated, that's how it comes, don't come for me 🙈), and the date on this one is October 2026. that's the version-and-date energy, periodt.

hope that cleared things up bestie, go forth and allocate responsibly 🧚💜
