igb_copper_link_setup_m88(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is a page straight out of the Kernel API Manual (yes, that's the manual name, we're being fancy today ✨), and it's all about getting the m88 PHY to behave for a copper link. pull up a chair bestie 🫶

🌸 NAME 🌸

igb_copper_link_setup_m88 — Setup m88 PHY's for copper link

like, that's literally the whole job. it sets up the m88 PHY. for the copper link. no cap 💖

✨ SYNOPSIS ✨

s32 igb_copper_link_setup_m88 (struct e1000_hw *hw );

returns an s32, takes a pointer, that's the vibe 💫

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. that's it. that's the whole argument list. give her the hardware struct and she'll handle the rest 🧚

🦋 DESCRIPTION 🦋

so what does she actually do? she Sets up MDI/MDI-X and polarity for m88 PHY's. iconic behavior, honestly 👑

and if it's necessary, transmit clock and downshift values are set also. conditional queen — she only does it when it's needed 💅 not out here doing extra work for no reason.

🔥 SEE ALSO 🔥

okay this list is LONG, but bestie, every single one matters, so we're not skipping ANY of them. not one. periodt 📋

she lives in the kernel file ./drivers/net/ethernet/intel/igb/e1000_phy.c — go say hi to her neighbors 🏡

lowkey a whole friend group of functions, go read them all, they're all in the kernel source, iykyk 💜

and that's the page, bestie 🎀✨
