💅 lpfc_issue_els_rscn — Kernel API Manual, bestie edition ✨

okay so you're looking at the manual page for lpfc_issue_els_rscn(9), and honestly? it's a little baddie. let's get into it 🎀

🌸 NAME 🌸

lpfc_issue_els_rscn — Issue an RSCN to the Fabric Controller (Fabric) or the other nport (pt2pt).

🦋 SYNOPSIS 🦋

int lpfc_issue_els_rscn (struct lpfc_vport *vport , uint8_t retry );

✨ ARGUMENTS ✨

  • vport — pointer to a host virtual N_Port data structure. your vport, your main character 👑
  • retry — number of retries to the command IOCB. like how many times you're willing to text back, fr fr.

💖 DESCRIPTION 💖

This routine issues a RSCN to the Fabric Controller (DID 0xFFFFFD) when you're connected to a fabric, or to the remote port when you're connected in point-to-point mode. so like, dependent on the situationship you're currently in 🫶

When it's sent to the Fabric Controller, it will replay the RSCN to the registered recipients. yes, it's giving group-chat forward energy 💀

Heads up bestie: the ndlp reference count will be incremented by 1 for holding the ndlp, and the reference to ndlp will be stored into the ndlp field of the IOCB for the completion callback function to the RSCN ELS command. like it's holding a spot for you at the function, iconic behavior.

Return code 0 - Successfully issued RSCN command, 1 - Failed to issue RSCN command. it's literally a vibe check that only has two outcomes 😭
