ice_xmit_zc(9)

💖 ice_xmit_zc(9) — the XSK-to-HW pipeline bestie 💖

okay so picture this: you're in the Kernel API Manual and this little function is literally the main character of moving packets. no cap.

---

✨ NAME ✨

ice_xmit_zc — the function that takes entries from the XSK Tx ring and places them onto the HW Tx ring. it's giving "matchmaker but for packets" fr fr 🎀

---

🌸 SYNOPSIS 🌸

bool ice_xmit_zc (struct ice_tx_ring *xdp_ring , struct xsk_buff_pool
*xsk_pool );

like, it returns a bool and takes two pointers. iconic signature tbh 💅

---

🦋 ARGUMENTS 🦋

• xdp_ring — the XDP ring where we're gonna produce the HW Tx descriptors. this is the glow-up station ✨
• xsk_pool — the AF_XDP buffer pool pointer. the vibes source, the stash, the pool 🏊‍♀️

---

🔥 DESCRIPTION 🔥

Returns true if there is no more work that needs to be done, false otherwise. that's it. that's the whole mood. a little boolean truth-teller and honestly? we stan 🫶

bestie don't overthink it — true = we're done, false = keep going, there's still stuff to do 💀
