🌸 NAME 🌸

ixgbe_check_for_ack_pf — checks to see if the VF has ACKed 👀✨

like literally that's her whole personality and honestly? iconic.

---

🦋 SYNOPSIS 🦋

int ixgbe_check_for_ack_pf (struct ixgbe_hw *hw , u16 vf_number );

yes she returns an int, yes she takes two args, no we're not debating it 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🖥️✨ this is the hardware bestie, she's holding everything together
• vf_number — the VF index 🔢 which virtual function are we talking about, be specific babes

💜 DESCRIPTION 💜

okay so here's the vibe: this function returns SUCCESS if the VF has set the Status bit 🌟 — and if not? it gives you ERR_MBX 💀 that's it. that's the whole tea. no cap.

so like, SUCCESS = she ACKed, ERR_MBX = she left you on read 🙈
