ixgbe_write_cs4227(9)

💖 NAME 💖

hey bestie, welcome to ixgbe_write_cs4227(9) from the Kernel API Manual — this is the function that does exactly what it says on the label: it writes a CS4227 register. iconic, brief, to the point ✨

✨ SYNOPSIS ✨

int ixgbe_write_cs4227 (struct ixgbe_hw *hw , u16 reg , u16 value );

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. the VIP pass to the hardware struct, fr fr 💅
• reg — register number to write. this is the register you're writing to, periodt
• value — value to write to register. the actual value going into that register 🫶

🦋 DESCRIPTION 🦋

okay so the description is short and iconic: it returns status code. that's it. that's the whole lore. not me expecting a novel and getting one line 😭

no cap, the page literally says:

Returns status code

so yeah — status code comes back, bestie. manifest that return value and go live your life ✨
