i40e_get_pfc_delay(9)

💅 i40e_get_pfc_delay(9)

okay so bestie, welcome to the Kernel API Manual — today's main character is i40e_get_pfc_delay(9), and honestly? She's short, she's sweet, she does exactly one (1) thing. Let's get into it. 🎀

---

✨ NAME ✨

i40e_get_pfc_delay — retrieve PFC Link Delay. that's it, that's the whole job, and she ate. 🦋

---

🌸 SYNOPSIS 🌸

void i40e_get_pfc_delay (struct i40e_hw *hw , u16 *delay );

like… look at her. returns void, takes two pointers, no drama, no notes. 💅

---

🫶 ARGUMENTS 🫶

• hw — pointer to hardware struct. yes girl, hand over the hardware, she needs it.
• delay — holds the PFC Link delay value. she's gonna put the number in here for you, bestie, that's the whole point. 🌟

---

💖 DESCRIPTION 💖

Returns PFC Link Delay from the PRTDCB_GENC.PFCLDA — that's the register field, keep it exactly like that, no cap. it's giving "one-line function with impeccable vibes." ✨

ngl it's a tiny function, but it's iconic tiny. she reads the field, she hands you the delay, she leaves. periodt. 👑
