🌸 NAME 🌸

i40e_xsk_clean_tx_ring — Clean the XDP Tx ring on shutdown

like… it's the cleanup crew. when things are shutting down, this is the function that comes in with the broom and makes the Tx ring all sparkly again. 💅

---

✨ SYNOPSIS ✨

void i40e_xsk_clean_tx_ring (struct i40e_ring *tx_ring );

no cap, that's the whole signature. takes one pointer, returns nothing (it's a void, she doesn't give anything back, she just ✨does the work✨).

---

🎀 ARGUMENTS 🎀

• tx_ring — the XDP Tx ring 💫 that's it, that's the one thing you pass in. it's a struct i40e_ring * and it's the ring that's getting cleaned.

🫶 just a heads up bestie: the manpage doesn't say anything about what happens if tx_ring is weird, so we're not gonna invent lore. keep it to what's written, iykyk.
