i40e_free_tx_resources(9)

okay bestie, welcome to the i40e_free_tx_resources(9) page from the Kernel API Manual 💖. This is the function that frees Tx resources per queue, and we’re keeping every detail intact — no cap.

✨ NAME ✨

i40e_free_tx_resources — Free Tx resources per queue. periodt.

🌸 SYNOPSIS 🌸

void i40e_free_tx_resources (struct i40e_ring *tx_ring );

So yeah: the synopsis says void, and it takes a struct i40e_ring *tx_ring. Iconic signature behavior.

🎀 ARGUMENTS 🎀

• tx_ring — Tx descriptor ring for a specific queue. That’s the one queue’s ring, bestie.

💖 DESCRIPTION 💖

Free all transmit software resources. That’s it — that’s the whole job. It’s giving “cleanup era” for the transmit-side software resources, fr fr.
