✨ ice_xmit_pkt_batch(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a lil function that lives in the networking gutters of the kernel, and honestly? it's giving "assembly line but make it DMA" 🏭✨

---

🌸 NAME 🌸

ice_xmit_pkt_batch — produce a batch of HW Tx descriptors out of AF_XDP descriptors 🔥

like, it takes a whole stack of AF_XDP descriptors and turns them into HW Tx descriptors in one go, because doing them one at a time is so last season 💀

---

🎀 SYNOPSIS 🎀

void ice_xmit_pkt_batch (struct ice_tx_ring *xdp_ring , struct xsk_buff_pool *xsk_pool , struct xdp_desc *descs , unsigned int *total_bytes );

she returns nothing (void, iconic, no notes) and takes four args 🫶

---

🦋 ARGUMENTS 🦋

• xdp_ring — the XDP ring you're producing the HW Tx descriptors on 🎯 that's the destination, the main character, the stage
• xsk_pool — the XSK buffer pool you pick the buffers from, aka the ones HW is gonna consume 👑
• descs — the AF_XDP descriptors you pull the DMA addresses and the lengths out of 🧚 gotta get both, no cap
• total_bytes — a bytes accumulator 📊 it's used for the stats update later, so pls keep it accurate bestie

lowkey a whole squad of zero-copy functions, and you thought your group chat was big 😭

that's the whole page bestie, go forth and batch those descriptors 🦋💖
