iavf_tx_map(9)

💅 iavf_tx_map(9) — bestie builds the Tx descriptor ✨

Okay so this is the iavf_tx_map(9) page from the Kernel API Manual, and it's basically the little function that builds the Tx descriptor. No cap, it's giving "one job, but make it count" energy. 🫶

🌸 NAME 🌸

iavf_tx_map — Build the Tx descriptor.

🦋 SYNOPSIS 🦋

void iavf_tx_map (struct iavf_ring *tx_ring , struct sk_buff *skb ,
       struct iavf_tx_buffer *first , u32 tx_flags , const u8 hdr_len , u32
       td_cmd , u32 td_offset );

✨ ARGUMENTS ✨

• tx_ring — the ring you're sending the buffer on, bestie. That's its whole vibe.
• skb — the send buffer itself. main character energy, honestly.
• first — the first buffer info buffer to use. yes, "first buffer info buffer" is the actual phrase, iykyk 😭
• tx_flags — the collected send information, all bundled up.
• hdr_len — size of the packet header. tiny but important 🎀
• td_cmd — the command field in the descriptor. very demure, very command-coded.
• td_offset — offset for checksum or crc. slay those checksums 💅
