📦 version 7.3.1, in nixpkgs unstable

💖 e1000e_get_phy_info_igp — the igp PHY info grabber 💖

okay bestie so this is a page from the Kernel API Manual (the 9 section, kernel dev vibes) and it's all about e1000e_get_phy_info_igp. she's a little function in the Intel e1000e driver family and she's here to spill the tea on your PHY. let's get into it 🫶

✨ NAME ✨

e1000e_get_phy_info_igp — literally the function that retrieves igp PHY information 💅

🌸 SYNOPSIS 🌸

s32 e1000e_get_phy_info_igp (struct e1000_hw *hw );

that's the whole signature, no cap. returns an s32, takes one pointer. periodt.

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. that's it, that's the whole argument list, she travels light 🦋

👑 DESCRIPTION 👑

okay so here's the lore. this function reads the PHY status to figure out if the link is up. simple enough, right?

if the link is up, then it sets/determines the 10base-T extended distance and polarity correction. yes bestie, polarity correction, she cares about your cable orientation ✨

then it reads the PHY port status to determine MDI/MDIx and speed. and based on that speed, it determines things about the cable length, plus the local and remote receiver. very main character energy of her honestly 🔥

🧚 SEE ALSO 🧚

and now the friend group, the whole entire squad, no one gets left out 💜:

like i said. the whole squad. every single one of them 💀
