ixgbe_mii_bu..._generic_c45(9)

💖 ixgbe_mii_bus_read_generic_c45 💖

okay bestie, gather round, because this one is a little kernel function called ixgbe_mii_bus_read_generic_c45 from the ixgbe_mii_bu..._generic_c45(9) manual page, and it is literally here to read a clause 45 register with gssr flags. no cap. it's giving "tiny driver helper with main character energy" and we are obsessed. 🦋

✨ SYNOPSIS ✨

int ixgbe_mii_bus_read_generic_c45 (struct ixgbe_hw *hw , int addr , int
devad , int regnum , u32 gssr );

like, that's the whole vibe. five arguments, one int coming back at you. slay. 💅

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. your hardware bestie, the whole reason we're here. 💖
• addr — address. just the address, periodt.
• devad — device address to read. this is the one you're reading from, iykyk. 🎯
• regnum — register number. the actual register, the main character. 👑
• gssr — semaphore flags to acquire. yes bestie, we're grabbing semaphore flags. handle with care. 🔥

ngl, if you're poking around this deep in the ixgbe PHY code, you already know what you're doing. keep slaying, and don't forget to check the file path up there. 🫶

🌸 okay that's the page!! this cutie came from ./drivers/net/ethernet/intel/i... and its version/date situation is October 2026, all wrapped up under the name ixgbe_mii_bu..._generic_c45(9). mwah, bye bestie 💜🎀
