igb_write_phy_reg_i2c(9)
π NAME π
okay bestie, welcome to igb_write_phy_reg_i2c(9) from the Kernel API Manual β yes, we're doing kernel networking today and it's lowkey iconic. The name is literally:
igb_write_phy_reg_i2c β write PHY register using i2c. periodt. π
π¦ SYNOPSIS π¦
here's the exact signature, no cap β keep the commas and spacing, they're canon:
s32 igb_write_phy_reg_i2c (struct e1000_hw *hw , u32 offset , u16 data
);
π ARGUMENTS π
hwβ pointer to the HW structure. literally the hardware struct you're handing over.offsetβ register offset to write to.dataβ data to write at register offset.
β¨ DESCRIPTION β¨
so what does it do? it writes the data to the PHY register at the offset using the i2c interface. that's the whole main character moment, fr fr. π

π SEE ALSO π
the kernel file to peek at is ./drivers/net/ethernet/intel/igb/e1000_phy.c β that's the one, bestie. and here's the whole friend group:
