💅 i40e_read_phy_register_clause45(9) — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and the star of the show is i40e_read_phy_register_clause45() ✨ (the page header up top is literally just vibes and truncation, i40e_read_p...ter_clause45(9), so, yeah, that's her name shortened for the runway 🎀).

🌸 NAME 🌸

i40e_read_phy_register_clause45 —

and honestly? that's it. that's the whole name section. the dash is just sitting there, no description, no nothing, a total main character with zero backstory 💀. we move on, she's mysterious.

🦋 SYNOPSIS 🦋

int i40e_read_phy_register_clause45 (struct i40e_hw *hw , u8 page , u16
reg , u8 phy_addr , u16 *value );

like, it returns an int, and it takes five whole arguments. she's lowkey high maintenance but she's worth it 🫶

🌈 ARGUMENTS 🌈

  • hw — pointer to the HW structure ✨ your hardware bestie, the whole context, the vibe.
  • page — registers page number 🍓 (it's a u8, so keep it smol and cute).
  • reg — register address in the page 💜 (a u16, a little roomier).
  • phy_addr — PHY address on MDIO interface 🌸 (also u8, also smol).
  • value — PHY register value 👑 — note the u16 *, it's a pointer, so the result gets written back out to you. that's the whole point, iykyk.

✨ DESCRIPTION ✨

Reads the specified PHY register value. that's it. that's the entire plot. short, sweet, iconic 💅. no cap, she does one (1) thing and she does it.

bestie note: value is a pointer, so this is where the answer lands. don't come for me, it's literally in the signature 🫶
