💅 lpfc_els_rcv_lcb — it's a Kernel API Manual situation, bestie

Okay so this little icon is a kernel API function called lpfc_els_rcv_lcb(9), and it lives in the Kernel API Manual, which is like the group chat archive for kernel functions. Let's get into it 🫶

✨ NAME ✨

lpfc_els_rcv_lcb — lowkey the function that handles an unsolicited LCB. That's the whole vibe.

🌸 SYNOPSIS 🌸

int lpfc_els_rcv_lcb (struct lpfc_vport *vport , struct lpfc_iocbq
*cmdiocb , struct lpfc_nodelist *ndlp );

Note the return type: it's an int. Everyone say thank you to the return type 😌

🎀 ARGUMENTS 🎀

Three besties walk into a function:

  • vport — a pointer to a host virtual N_Port data structure. Basically the VIP pass 🪪
  • cmdiocb — a pointer to the lpfc command iocb data structure. The main-character command object fr fr.
  • ndlp — a pointer to a node-list data structure. The whole node situation, gorgeous.

🦋 DESCRIPTION 🦋

So this routine's entire personality is processing an unsolicited LCB (LINK CABLE BEACON) IOCB. Literally what it says on the tin, no cap.

Here's the little routine's journey:

  1. First, the payload of the unsolicited LCB gets checked. Yes, it's doing a vibe check on the payload 🔍
  2. Then, based on the Subcommand, the beacon will either turn on or turn off. That's it. That's the plot. Iconic.

And for the return codes, slay:

  • Return code 0 — Sent the acc response ✅
  • Return code 1 — Sent the reject response 💀

👑 SEE ALSO 👑

Okay bestie, buckle up, because this cross-reference list is long and it ate. Periodt. Every single one of these, preserved exactly:

And the kernel file it all hangs out in: ./drivers/scsi/lpfc/lpfc_els.c 🧚

Ngl, that's a lot of cross-references for one beacon function, but we respect the hustle 💜

Okay that's the whole page, bestie — mwah 💋 This adorable little doc came from the source path ./drivers/scsi/lpfc and it's dated October 2026, so mark your calendars fr fr. Byeeeee 🌈✨🍓
