fm10k_mbx_process_connect(9)

📦 version 7.3.1, in nixpkgs unstable

💖 fm10k_mbx_process_connect(9) 💖

okay bestie, welcome to the Kernel API Manual, section 9 — this one's a lil function from the fm10k driver and honestly? she's kind of a big deal in the mailbox world. let's get into it 🫶

✨ NAME ✨

fm10k_mbx_process_connect — the one that processes the connect header 🎀

🌸 SYNOPSIS 🌸

s32 fm10k_mbx_process_connect (struct fm10k_hw *hw , struct
       fm10k_mbx_info *mbx );

like, that's the whole signature. s32 in, s32 out, two pointers in the middle. slay. 💅

🦋 ARGUMENTS 🦋

  • hw — pointer to hardware structure ✨ (yes she needs to know about the actual hardware, it's giving main character energy)
  • mbx — pointer to mailbox 💌 (the mailbox in question, iconic)

🌈 DESCRIPTION 🌈

so here's the vibe: this function reads an incoming connect header and then replies with the appropriate message. that's the whole job. not me thinking that's lowkey efficient 🙈

and then it tells you how it went:

  • on success it returns a value indicating the number of data DWORDs 🎉
  • on failure it returns a negative value 😭 (as is tradition)

fr fr, that's it. short queen behavior. 👑

🧚 SEE ALSO 🧚

okay so this is the part where the manpage just. lists. everything. and we are NOT skipping a single one, because every single reference is a baddie in her own right 💜

the kernel file itself:

  • Kernel file ./drivers/net/ethernet/intel/fm10k/fm10k_mbx.c

and then the entire sm_mbx extended universe 🌌:

like. that's the whole friend group. no one left out. periodt. 💅✨

ngl the footer path got truncated by the manpage renderer, so it shows as ./drivers/net/ethernet/intel/f... — that's the source/version line, bestie, not a typo on my part 🫶

and that's the page!! brought to you by the Kernel API Manual, dated October 2026, section 9, fm10k_mbx_process_connect(9) — mwah, love u, go read your mailboxes responsibly 💖🎀🦋
