💅 idpf_xdp_tx_xmit(9) 💅

okay so bestie, we're in the Kernel API Manual for this one, and the main character is idpf_xdp_tx_xmit. It's a void function and its whole vibe is literally right here 👇

🌸 NAME 🌸

idpf_xdp_tx_xmit — produce a single HW Tx descriptor out of XDP desc

✨ SYNOPSIS ✨

void idpf_xdp_tx_xmit (struct libeth_xdp_tx_desc desc , u32 i , const
       struct libeth_xdpsq *sq , u64 priv );

That's the whole signature, no cap. Four arguments, one void return, and all the deets are below 🫶

🎀 ARGUMENTS 🎀

• desc — the XDP descriptor you're pulling the DMA address and length from. it's giving "source material" 💅
• i — the descriptor index on the queue to fill. basically the slot number, iykyk.
• sq — the XDP queue where you produce the HW Tx descriptor. this is the queue bestie, main character energy 🌈
• priv — xsk_tx_metadata_ops on XSk xmit or NULL. so it's either that metadata ops situation or literally NULL, periodt.
