i40e_xsk_pool_setup(9)

🌸 NAME 🌸

i40e_xsk_pool_setup — Enable/disassociate an AF_XDP buffer pool to/from a ring/qid

okay bestie, welcome to the i40e_xsk_pool_setup(9) page from the Kernel API Manual. It’s giving kernel-level matchmaking: we’re hooking a buffer pool up to a ring, or breaking them up. 💅

---

✨ SYNOPSIS ✨

int i40e_xsk_pool_setup (struct i40e_vsi *vsi , struct xsk_buff_pool
       *pool , u16 qid );

---

🎀 ARGUMENTS 🎀

• vsi — the current VSI. Yes, that one. The VSI you’re working with right now. 🫶
• pool — the buffer pool to enable/associate to a ring, or NULL to disable it. So NULL is the “we’re not together anymore” option. 💔
• qid — the Rx ring to (dis)associate the buffer pool (from)to. That’s the exact wording, bestie — we don’t edit the lore. 👑

---

💖 DESCRIPTION 💖

This function enables or disables a buffer pool to a certain ring. That’s the whole vibe: flip it on for the ring, or flip it off. 🔥

It returns 0 on success, and <0 on failure. So 0 is the slay, and anything below 0 is the “bestie, something went wrong” zone. 😭
