✨ i40e_ptp_set_increment ✨

okay so bestie, welcome to the kernel API manual page for i40e_ptp_set_increment — yes it's a mouthful, no you don't have to say it out loud 💅

💖 NAME 💖

i40e_ptp_set_increment — a lil utility function that goes and updates the clock increment rate 🕰️✨

🦋 SYNOPSIS 🦋

void i40e_ptp_set_increment (struct i40e_pf *pf );

🌸 ARGUMENTS 🌸

  • pf — the board private structure 🫶 (yes, that's really all it says, she's a simple girlie)

🎀 DESCRIPTION 🎀

okay so picture this: a link change happens, right? and when that goes down, the DMA frequency that drives the 1588 logic also changes 🔥

and because we are absolutely not about to let the PRTTSYN_TIME registers lose their nanoseconds units (iconic of them btw, keeping it consistent), we must update the increment value per clock tick. that's literally the whole job. no cap. 💀

👑 SEE ALSO 👑

the kernel file lives right here, bestie:

./drivers/net/ethernet/intel/i40e/i40e_ptp.c

and here's the whole extended fam — every single one of them, no skipping, iykyk 🌈:

ok that's the whole page bestie, go forth and keep those nanoseconds accurate 🧚💜

and finally, the cute lil sign-off: this one comes from ./drivers/net/ethernet/intel/i40e, dated October 2026 — mwah, periodt 💅🎀
