✨ e1000_check_polarity_ife — check cable polarity for IFE PHY ✨

okay so bestie, welcome to the e1000_check_polarity_ife(9) page from the Kernel API Manual 💖 this one is a little function from the depths of the intel ethernet driver, and honestly? she's giving "small but essential" energy 🎀

🌸 NAME 🌸

e1000_check_polarity_ife — literally just checks the cable polarity for the IFE PHY 🦋

🎀 SYNOPSIS 🎀

s32 e1000_check_polarity_ife (struct e1000_hw *hw );

💅 ARGUMENTS 💅

okay this list is LONG, like long long, so grab a snack 🍓 and let's go — these are all siblings in Kernel file ./drivers/net/ethernet/intel/e1000e/phy.c:

like I said. iconic list. ate. 👑

ngl bestie, nothing scary in here — no return values documented, no errors, no bugs, no env vars. just vibes and one very specific PHY check 💅

and that's the page!! 🧚 this little cutie lives in ./drivers/net/ethernet/intel/e... (they truncated it in the footer, not me 🙈) and the footer stamps her as October 2026, Kernel API Manual, version e1000_check_polarity_ife(9) — mwah, periodt 💖🌸
