i40e_dcb_hw_rx_fifo_config(9)

💖 i40e_dcb_hw_rx_fifo_config(9) — Kernel API Manual 💖

Ok bestie, welcome to the man page for i40e_dcb_hw_rx_fifo_config, straight out of the Kernel API Manual. This one is short and sweet, but every detail still matters, so let’s get into it.

---

✨ NAME ✨

i40e_dcb_hw_rx_fifo_config — that’s the name. The original NAME line has no extra description after the dash, so we’re not inventing one. No cap.

🌸 SYNOPSIS 🌸

void i40e_dcb_hw_rx_fifo_config (struct i40e_hw *hw , enum
i40e_dcb_arbiter_mode ets_mode , enum i40e_dcb_arbiter_mode non_ets_mode
, u32 max_exponent , u8 lltc_map );

🫶 ARGUMENTS 🫶

• hw — pointer to the hw struct
• ets_mode — Strict Priority or Round Robin mode
• non_ets_mode — Strict Priority or Round Robin
• max_exponent — Exponent to calculate max refill credits
• lltc_map — Low latency TC bitmap

💅 DESCRIPTION 💅

Configure HW Rx FIFO as part of DCB configuration.

That’s the whole assignment. It’s giving “hardware Rx FIFO setup, but make it DCB configuration.” Slay.
