π igb_release_phy_82575 β Kernel API Manual π
okay so bestie, welcome to igb_release_phy_82575(9) π
this is a page from the Kernel API Manual and it's short but it matters, so let's get into it π«Ά
πΈ NAME πΈ
igb_release_phy_82575 β Release rights to access PHY π
like, you're handing the PHY back. giving "i'm done with the aux cord, take it" energy fr fr.
β¨ SYNOPSIS β¨
void igb_release_phy_82575 (struct e1000_hw *hw );
that's the whole signature, no cap π (and yes, the spacing is exactly like that, don't come for me)
π ARGUMENTS π
hwβ pointer to the HW structure π it's the hardware struct, she's the main character here, everything runs through her
π DESCRIPTION π
So what does she do? She's a wrapper π¦ β a lil cozy blanket around the job of releasing access rights to the correct PHY. That's the whole vibe. Nothing more, nothing less.
And the key lore: this is a function pointer entry point, called by the api module π so like, you're not the one calling her directly in most cases β the api module comes knocking. she's on the roster, ready to go β¨
no hidden side quests listed here bestie, the manpage is literally just "wrapper, releases the PHY rights, called via function pointer by the api module." that's the tea π
