i40e_dcbnl_set_pfc_cfg(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_dcbnl_set_pfc_cfg — like, the Kernel API Manual entry, bestie

okay so welcome to the glow-up of i40e_dcbnl_set_pfc_cfg(9), straight out of the Kernel API Manual. this one's short and sweet and it's giving "tiny function, big responsibilities." let's get into it ✨

🌸 NAME 🌸

i40e_dcbnl_set_pfc_cfg — Set CEE PFC configuration. that's it. that's the whole name. no cap, it does exactly what it says on the tin 🎀

🦋 SYNOPSIS 🦋

void i40e_dcbnl_set_pfc_cfg (struct net_device *netdev , int prio , u8
setting );

notice the void?? this one doesn't return anything, she just does the thing and leaves. main character energy honestly 💅

✨ ARGUMENTS ✨

three little besties walk into a function:

  • netdev — the corresponding netdev. your network device, the whole reason we're here 🫶
  • prio — the corresponding user priority. which priority we're talking about, be specific pls 🙈
  • setting — the PFC setting for that given priority. the actual value, the moment, the whole point ⭐

🌈 DESCRIPTION 🌈

okay so this function sets the PFC enabled/disabled setting for a given user priority. that's the tea. that's the whole description. it's a setter, it sets, it slays 🍓

lowkey iconic that a manpage this small still gets the job done fr fr. no extra lore, no secret plotline, just: netdev + prio + setting → the PFC setting for that priority gets set. periodt 💖
