iavf_tso(9)

🌸 NAME 🌸

Okay bestie, welcome to the iavf_tso(9) page from the Kernel API Manual — this one is literally iavf_tso and its whole name-brand job is: set up the tso context descriptor 💅✨

✨ SYNOPSIS ✨

int iavf_tso (struct iavf_tx_buffer *first , u8 *hdr_len , u64 *cd_type_cmd_tso_mss );

🎀 ARGUMENTS 🎀

• first — pointer to first Tx buffer for xmit 🚀
• hdr_len — ptr to the size of the packet header 📏
• cd_type_cmd_tso_mss — Quad Word 1 👑

🦋 DESCRIPTION 🦋

Return-value tea, no cap: it returns 0 if no TSO can happen, 1 if tso is going, or error. That’s the vibe check for this one, fr fr 🫶
