ice_fill_tx_hw_ring(9)

💅 NAME

ice_fill_tx_hw_ring — okay so this is the girlie that produces the number of Tx descriptors onto the ring. Slay. ✨

This page lives in the Kernel API Manual, which is giving very "iykyk, kernel edition" energy 🎀

🌸 SYNOPSIS

void ice_fill_tx_hw_ring (struct ice_tx_ring *xdp_ring , struct
       xsk_buff_pool *xsk_pool , struct xdp_desc *descs , u32 nb_pkts ,
       unsigned int *total_bytes );

Like literally that's the whole signature, no cap. 🫶

✨ ARGUMENTS

Miss thing takes five arguments and honestly? She needs all of them. Here's the breakdown bestie:

• _xdp_ring_ — the XDP ring to produce the HW Tx descriptors on. This is the main character of the operation, fr fr 👑
• _xsk_pool_ — the XSK buffer pool to pick buffers to be consumed by HW. Think of it as the lil stash of snacks 🍓 that hardware is gonna munch on.
• _descs_ — the AF_XDP descriptors to pull the DMA addresses and lengths from. So she's grabbing the actual addresses + lengths outta here 💅
• _nb_pkts_ — count of packets to be send. That's the number of packets, periodt. (Yes the original says "send" and not "sent", we respect the source 😭)
• _total_bytes_ — bytes accumulator that will be used for stats update. She's the running total, keeping receipts for the stats 💀

Not me ending the whole page btw 🫶 this one came out of ./drivers/net/ethernet/intel/ice and it's dated October 2026, and she's very much ice_fill_tx_hw_ring(9) through and through. Obsessed, honestly. 🌈⭐💖
