qed_mcp_ack_vf_flr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 qed_mcp_ack_vf_flr — a kernel API manual, but make it make sense

Hey bestie 🫶 so this is a page from the Kernel API Manual (section 9, the function-page girlies) and it's all about qed_mcp_ack_vf_flr. Yes that's a mouthful, yes it's iconic, no we're not skipping a single line of it. Let's go ✨

🌸 NAME 🌸

qed_mcp_ack_vf_flr — the function that acks to mfw that the driver finished the FLR process for VFs. That's it. That's the whole job. She's a one-task queen 👑

🎀 SYNOPSIS 🎀

int qed_mcp_ack_vf_flr (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt
, u32 *vfs_to_ack );

So she takes three things and gives you back an int. Simple. Clean. No cap 💅

🦋 ARGUMENTS 🦋

Okay so here's the trio of parameters, and every single one matters:

  • p_hwfn — HW device data. The hardware's whole little identity card, basically 🪪
  • p_ptt — P_ptt. Yep, that's the description, that's what it is. Short and mysterious, we love a lowkey king 🙈
  • vfs_to_ack — the bit mask of all the engine VFs for which the PF acks. Every VF getting an ack is a lil bit lit up in there ⭐

🔥 RETURN 🔥

Int — and 0 means the operation was successul ✨ (that's literally how the page spells it — the typo is part of the lore now, we respect it 😭). So: 0, you're golden. That's the return story, bestie.

💜 SEE ALSO 💜

Strap in, this list is long — she has a whole extended friend group and we're naming every single one of them, because nobody gets left out on my watch 🫶

First, the file she lives in:

Kernel file ./drivers/net/ethernet/qlogic/qed/qed_mcp.h

And now the full squad, in order, no skips, no merges:

That's 68 references, bestie. Sixty-eight. She's not a function, she's a networking event 🌈

and that's the whole page, start to finish, nothing dropped 💖

Cute lil sign-off: this masterpiece comes from ./drivers/net/ethernet/qlogic/qed, dated October 2026, and she's filed under qed_mcp_ack_vf_flr(9) — go ack those VFs, you absolute main character 👑🦋
