igb_get_phy_info_igp(9)
π NAME π
okay so this is igb_get_phy_info_igp β the igp PHY information getter β straight out of the Kernel API Manual, section 9, bestie π¦. It's giving βretrieve igp PHY information,β and honestly that's the whole vibe.
β¨ SYNOPSIS β¨
s32 igb_get_phy_info_igp (struct e1000_hw *hw );
π ARGUMENTS π
hwβ pointer to the HW structure. That's it, one pointer, no drama π
πΈ DESCRIPTION πΈ
Okay so what does it actually do? It reads PHY status to determine if the link is up. If the link is up, then it sets/determines 10base-T extended distance and polarity correction. Then it reads PHY port status to determine MDI/MDIx and speed. Based on the speed, it determines cable length, local receiver, and remote receiver. Literally a whole tiny detective arc in one function, and I'm obsessed π₯.
