💅 pch_gbe_mac_ctrl_miim(9) — Control MIIM interface

okay so bestie, welcome to the Kernel API Manual page for pch_gbe_mac_ctrl_miim. yeah it's a mouthful, just say it with confidence ✨ This is the little function that controls the MIIM interface — that's the management-data door the driver uses to chat with the PHY. She's giving "phone operator for the network card" energy, and honestly? iconic. 🎀

✨ SYNOPSIS ✨

u16 pch_gbe_mac_ctrl_miim (struct pch_gbe_hw *hw , u32 addr , u32 dir ,
u32 reg , u16 data );

she returns a u16, she takes five args, and she is not here to explain herself 💅

🌸 ARGUMENTS 🌸

  • hw — Pointer to the HW structure. you know, the hardware. the whole vibe provider. 🫶
  • addr — Address of PHY. which PHY we're talking to, bestie, they don't all share a phone line 💖
  • dir — Operetion. (Write or Read) — yes, the manual literally says "Operetion", and no I will not be fixing it, it's canon now 💀 it's the direction: are we writing or reading.
  • reg — Access register of PHY. which register on that PHY we're poking at 👑
  • data — Write data. the actual payload, the moment of truth, the main character 🌟

⭐ RETURN ⭐

Read date.

ngl that's what it says — "Read date." — it means read data, and honestly the typo has been living rent-free in my head ever since 😭 So: this returns the data that got read. slay.

quick vibe check: every one of those (9) refs is exactly how it's written in the source page, so don't come for me about the parentheses okay 😭 I don't make the rules, I just make them cute.

and that's the page!! tysm for reading, you ate that ngl 🍓 this little transmission was brought to you by Kernel API Manual, source ./drivers/net/ethernet/oki-sem..., dated October 2026, and of course the star herself pch_gbe_mac_ctrl_miim(9). mwah, bye bestie 💖🎀🦋
