✨ ice_calc_fixed_rx_offset_e82x ✨

okay so this is a page from the Kernel API Manual (yes, the (9) section, kernel-internals girlies rise 🫶), and it's about one very specific little function. bestie, it's a one-job function and honestly? it ate. let's get into it 💅

🌸 NAME 🌸

ice_calc_fixed_rx_offset_e82x — calculated the fixed Rx offset for a port ✨

(that's it. that's the whole personality. and we respect it.)

🎀 SYNOPSIS 🎀

u64 ice_calc_fixed_rx_offset_e82x (struct ice_hw *hw , enum ice_ptp_link_spd link_spd );

like, look at her. returns a u64, takes two things, minds her own business. main character energy fr fr 💖

🦋 ARGUMENTS 🦋

  • hw — pointer to HW struct. yes queen, hand over the hardware struct, that's where all the good stuff lives 👑
  • link_spd — The Link speed to calculate for. so tell her which speed you care about and she'll do the math for that one 🌈

💜 DESCRIPTION 💜

Determine the fixed Rx latency for a given link speed.

that's the whole vibe. you give her a link speed, she gives you back the fixed Rx latency for it. no cap, that's literally the entire function — she's not doing side quests, she's not doing extra credit, she's just doing the one thing and doing it correctly ✨

lowkey important detail: the return type is u64, so the answer comes back as an unsigned 64-bit value. that's the shape of the tea 🍓

💀 SEE ALSO 💀

okay so this is the part where the manpage just. lists. everyone. and I mean everyone. the whole ice PTP friend group showed up to the function's birthday party 😭🎀

the kernel file it lives in:

  • ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c

and now, the group chat roll call (do not skip, everyone gets named):

like. that's the whole extended universe. no notes. iykyk 🧚💫

and that's the page, bestie!! 💖 source/version tea: this one comes from ./drivers/net/ethernet/intel/ice, and it's dated October 2026 — so yeah, she's from the future and she's still just calculating that fixed Rx offset. iconic behavior honestly. slay, periodt, goodnight 🌙🎀💅
