ice_cfg_xps_tx_ring(9)

💅 ice_cfg_xps_tx_ring(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a lil function page from the kernel docs and it's honestly kind of a one-job icon. let me walk you through it 🫶

---

🌸 NAME 🌸

ice_cfg_xps_tx_ring — Configure XPS for a Tx ring

like. that's the whole personality. it configures XPS. for a Tx ring. slay 💅

---

✨ SYNOPSIS ✨

void ice_cfg_xps_tx_ring (struct ice_tx_ring *ring );

that's it. no return value, bestie — it's a void function, so it gives you nothing back and honestly that's main character energy 👑

---

🎀 ARGUMENTS 🎀

• ring — The Tx ring to configure. that's the one (1) thing you hand it. give it your Tx ring and it goes to work 🦋

---

💖 DESCRIPTION 💖

so what does it actually do? okay so: this enables/disables XPS for a given Tx descriptor ring, and it makes that call based on the TCs that are enabled for the VSI that ring belongs to. no cap, that's the whole bit 🔥

it's giving "small function, big context" — the ring itself doesn't decide anything, it's the VSI's TC situation that's calling the shots 👑

ngl, "XPS" and "TCs" and "VSI" is a lot of acronyms in one sentence, but that's literally what the page says so I'm not gonna invent lore 💀
