iavf_create_tx_ctx(9)

✨ NAME ✨

iavf_create_tx_ctx(9) — yes bestie, that’s the manual name — is a Kernel API Manual function that builds the Tx context descriptor. It’s giving “small helper, very important descriptor energy” 🎀

🌸 SYNOPSIS 🌸

Here’s the exact signature, bb — do not freestyle the types or the order:

void iavf_create_tx_ctx (struct iavf_ring *tx_ring , const u64
       cd_type_cmd_tso_mss , const u32 cd_tunneling , const u32 cd_l2tag2 );

💅 ARGUMENTS 💅

• tx_ring — the ring where you’re creating this descriptor. Put the descriptor on that ring, okay? 💖
• cd_type_cmd_tso_mss — Quad Word 1. That’s the whole note; it’s literally Quad Word 1. ✨
• cd_tunneling — Quad Word 0 - bits 0-31. Keep those bits exactly where they live. 🫶
• cd_l2tag2 — Quad Word 0 - bits 32-63. Same Quad Word 0, but the upper bits, bestie. 🦋

🔥 SEE ALSO 🔥

The kernel file for this one is ./drivers/net/ethernet/intel/iavf/iavf_txrx.c — that path is exact, don’t play with it. 😌
