π ixgbe_read_phy_reg_generic π
okay bestie, so this is a page from the Kernel API Manual and it's about ixgbe_read_phy_reg_generic β literally the function that reads a value from a specified PHY register using the SWFW lock, and the man page is out here saying straight up: this function is needed in most cases. like, main character energy fr fr, you're gonna be calling this one a lot π
β¨ SYNOPSIS β¨
int ixgbe_read_phy_reg_generic (struct ixgbe_hw *hw , u32 reg_addr , u32
device_type , u16 *phy_data );
that's it, that's the whole vibe check: takes some stuff, gives you back an int. π«Ά
π ARGUMENTS π
hwβ pointer to hardware structure. it's the whole hardware situation, she knows things πreg_addrβ the 32 bit address of the PHY register you wanna read. like a little address label on the exact register you're snooping on β¨device_typeβ the 5 bit device type. five bits, tiny, iconic, does a lot ngl π¦phy_dataβ pointer to read data from PHY register. the data literally gets read into whatever this points at, so bestie please make sure it points somewhere real π
