ice_calc_fi..._offset_e82x(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

okay so bestie, this is ice_calc_fixed_tx_offset_e82x β€” it calculates the Fixed Tx offset for a port ✨ that's the whole vibe, no cap.

(this one lives in the Kernel API Manual, section 9 β€” iykyk 🫢)


πŸŽ€ SYNOPSIS πŸŽ€

u64 ice_calc_fixed_tx_offset_e82x (struct ice_hw *hw , enum ice_ptp_link_spd link_spd );

like… it takes two things and gives you back a u64. iconic honestly πŸ’–


πŸ¦‹ ARGUMENTS πŸ¦‹

  • hw β€” pointer to the HW struct πŸ’… yeah she wants the whole hardware struct, not just a nibble
  • link_spd β€” the Link speed to calculate for ⚑ the exact speed you're doing the math for, bestie

🌸 DESCRIPTION 🌸

the way that this just… calculates the fixed offset due to known static latency data ✨ that's it, that's the function. known static latency data β†’ fixed offset, main character energy fr fr 🧚


πŸ”₯ SEE ALSO πŸ”₯

first up, she's hanging out in the kernel file ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c β€” go say hi πŸ‘‘

and then bestie… the friend group. the whole entire friend group. every single one of these, present and accounted for, not one dropped πŸ’€πŸ’–

ok so quick recap so you don't @ me later: the function name got truncated in the header to ice_calc_fi..._offset_e82x(9) β€” that's just the page header being dramatic and running out of room, the actual name is the full one up top πŸŽ€

and that's the whole page bestie!! source/version is from ./drivers/net/ethernet/intel/ice, dated October 2026, and it's filed under ice_calc_fi..._offset_e82x(9) πŸ’–βœ¨ slay, go calculate your offsets, ily 🫢🌈
