✨ xsk_tx_metadata_to_compl(9) ✨

okay so this is a page from the Kernel API Manual and honestly it's a little gem — it's all about stashing the right metadata so your TX completion can slay later. like a lil time capsule for your packets 💅

---

🎀 NAME 🎀

xsk_tx_metadata_to_compl — save enough relevant metadata information to perform tx completion in the future.

no cap, that's the whole vibe: future-you needs receipts, this function gets you the receipts 💖

---

🦋 SYNOPSIS 🦋

void xsk_tx_metadata_to_compl (struct xsk_tx_metadata *meta , struct
xsk_tx_metadata_compl *compl );

two pointers in, nothing out (it's void, bestie — it's giving silent but powerful) ✨

---

🌸 ARGUMENTS 🌸

• meta — pointer to AF_XDP metadata area
• compl — pointer to output struct xsk_tx_metadata_to_compl

that's it. two pointers. iconic. 🫶

---

💫 DESCRIPTION 💫

so this function should be called by the networking device when it prepares an AF_XDP egress packet. the value of compl should be stored and passed to xsk_tx_metadata_complete upon TX completion.

literally that's the whole plot: take the metadata, squish the relevant bits into compl, hang onto it, and hand it back over to xsk_tx_metadata_complete when the TX is done. don't lose it, bestie — it's the whole point 😭

fr fr: the whole deal is that compl gets stored now and used later at completion time. that's the contract, no cap.
