igb_ptp_tx_hwtstamp(9)

📦 version 7.3.1, in nixpkgs unstable

💅 igb_ptp_tx_hwtstamp 💅

ok so bestie, we're in the Kernel API Manual today (yes, the kernel, main character energy only) and the function we're stanning is igb_ptp_tx_hwtstamp 🎀

✨ NAME ✨

igb_ptp_tx_hwtstamp — a little utility function whose whole job is checking for a TX time stamp 🕐✨

🦋 SYNOPSIS 🦋

void igb_ptp_tx_hwtstamp (struct igb_adapter *adapter );

that's it. that's the whole signature. no cap. 💀

🌸 ARGUMENTS 🌸

  • adapter — the board private structure 🫶 like, the whole board's little private diary of a struct. everything it needs to know about itself lives in there.

🔥 DESCRIPTION 🔥

ok so here's the vibe 😌 if we were asked to do hardware stamping, and a time stamp like that is actually available? then it must have been for this skb right here — because we only allow only one such packet into the queue at a time. periodt. 👑

so like, there's no "which packet was this for 🤔" detective work happening. the queue is a strict one-in-one-out situation, so the stamp can only belong to the one packet we let in. it's giving exclusive 💅 absolutely no queue drama, no confusion, just vibes and a guaranteed one-to-one match. ngl it's kind of iconic how simple that is 🌈
