i40e_dcb_hw_pfc_config(9)

okay so bestie, welcome to i40e_dcb_hw_pfc_config(9) from the Kernel API Manual — manual name folded in right here like a lil name tag. 🎀

💖 NAME 💖

i40e_dcb_hw_pfc_config — that's the function, front and center. The original NAME line is just the name plus a dash with nothing after it, so we are not inventing a tagline. Periodt. 💅

🌸 SYNOPSIS 🌸

Here's the whole signature, character for character:

void i40e_dcb_hw_pfc_config (struct i40e_hw *hw , u8 pfc_en , u8 *prio_tc );

🦋 ARGUMENTS 🦋

• hw — pointer to the hw struct ✨
• pfc_en — bitmap of PFC enabled priorities 🫶
• prio_tc — priority to tc assignment indexed by priority 💅

✨ DESCRIPTION ✨

This one configures the HW Priority Flow Controller as part of DCB configuration. That's the assignment, and she ate. 🔥 No extra lore, no secret side quests — just that exact job. 🌟

Cute lil sign-off before you go: the source/version is ./drivers/net/ethernet/intel/i40e, the date is October 2026, and the manual page is still i40e_dcb_hw_pfc_config(9). bye bestie, go configure that HW Priority Flow Controller as part of DCB configuration 💅✨🎀
