ixgbe_init_...nature_82599(9)

🦋 NAME 🦋

okay so welcome to the Kernel API Manual bestie, section 9, and today's main character is ixgbe_init_fdir_signature_82599 — it initializes Flow Director signature filters 💅 (yes the page header squishes the name down to ixgbe_init_...nature_82599(9) but that's just the fancy abbreviated fit-on-the-label version, the real one is the full thing above ✨).

🌸 SYNOPSIS 🌸

int ixgbe_init_fdir_signature_82599 (struct ixgbe_hw *hw , u32 fdirctrl );

like that's it, that's the whole call signature, no cap 🔥

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure 🫶 literally a pointer to the hardware struct, that's the whole vibe
• fdirctrl — value to write to the flow director control register, initially contains just the value of the Rx packet buffer allocation 💖 so at first it's carrying only the Rx packet buffer allocation value, and then it goes into the flow director control register, iykyk
