ice_ptp_port_cmd(9)

💅 ice_ptp_port_cmd(9) — Kernel API Manual 💅

💅 NAME 💅

ice_ptp_port_cmd — Prepare PHY ports for a timer sync command. This is the ice_ptp_port_cmd(9) page, bestie, and it's giving “tiny function, big port-prep energy” ✨.

✨ SYNOPSIS ✨

int ice_ptp_port_cmd (struct ice_hw *hw , enum ice_ptp_tmr_cmd cmd );

🫶 ARGUMENTS 🫶

• hw — pointer to HW struct. Literally a pointer to the hardware struct, no cap.
• cmd — the timer command to setup. This is the timer command you're setting up.

🌸 DESCRIPTION 🌸

Okay so this function prepares all PHY ports on this device for the requested timer command. For some families this can be done in one shot, but for other families each port must be configured individually. That's the whole vibe 💅.

💅 RETURN 💅

• 0 — success. Slay, we love a clean return.
• other — failed to write port command. Not slay, but very useful to know 😭.
