igb_check_polarity_m88(9)

🌸 NAME 🌸

okay so bestie, this is the igb_check_polarity_m88(9) page from the Kernel API Manual — and it checks the polarity. that's the whole vibe check. 💅

✨ SYNOPSIS ✨

s32 igb_check_polarity_m88 (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🫶

🦋 DESCRIPTION 🦋

so here's the return sitch, no cap: Success returns 0; Failure returns -E1000_ERR_PHY (-2). periodt. 💖

Polarity is determined based on the PHY specific status register. that register is literally the main character here. ✨

bye bestie 🫶 this page came from ./drivers/net/ethernet/intel/igb, dated October 2026, and yeah the manual name is igb_check_polarity_m88(9) — iconic. 💖
