igb_ptp_tx_work(9)

💖 NAME 💖

okay so this is igb_ptp_tx_work(9), straight out of the Kernel API Manual. The NAME line is literally just igb_ptp_tx_work - with nothing after the dash — no description given, no cap, we are not making one up. 💅

✨ SYNOPSIS ✨

here’s the signature, exactly as it appears:

void igb_ptp_tx_work (struct work_struct *work );

🫶 ARGUMENTS 🫶

• work — pointer to work struct. That’s it, that’s the argument, bestie. 🎀

🌸 DESCRIPTION 🌸

So this work function polls the TSYNCTXCTL valid bit. Why? To determine when a timestamp has been taken for the current stored skb. That’s the whole mission of the page: poll the valid bit, figure out the timestamp status for the current stored skb. 🦋

lowkey important: the page does not give extra behavior beyond that, so I’m not adding lore. 💅
