i40e_ptp_rx_hang(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the i40e_ptp_rx_hang(9) Kernel API Manual moment πŸ’–. This is the page for the i40e_ptp_rx_hang function, and the whole vibe is catching one very specific timestamp-hang situation. fr fr.

✨ NAME ✨

i40e_ptp_rx_hang β€” detect the error case when the Rx timestamp registers are hung 🫢. That's the name, no cap.

🌸 SYNOPSIS 🌸

void i40e_ptp_rx_hang (struct i40e_pf *pf );

that's the signature, bestie β€” don't change a single character ✨.

πŸŽ€ ARGUMENTS πŸŽ€

  • pf β€” the PF private data structure. yes, that PF. the main-character struct of this page πŸ‘‘.

πŸ’… DESCRIPTION πŸ’…

okay so this watchdog task is scheduled to detect an error case: the hardware has dropped an Rx packet that was timestamped when the ring is full 😭. That's the specific little tragedy it's hunting for.

This particular error is rare, but it leaves the device in a state unable to timestamp any future packets. so it's rare but highkey rude to the device's timestamping abilities πŸ’€.
