📦 version 7.3.1, in nixpkgs unstable

💅 lpfc_issue_fabric_reglogin 💅

okay so bestie, we're in the Kernel API Manual, section 9, and today's main character is lpfc_issue_fabric_reglogin. pull up a chair, this one's a little baddie that gets your vport officially registered with the fabric ✨

🌸 NAME 🌸

lpfc_issue_fabric_reglogin — literally just: issue a fabric registration login for a vport. that's the whole vibe. 🦋

🎀 SYNOPSIS 🎀

int lpfc_issue_fabric_reglogin (struct lpfc_vport *vport );

🧚 ARGUMENTS 🧚

  • vport — pointer to a host virtual N_Port data structure. like, the vport in question. the one we're doing all this for. 💖

👑 DESCRIPTION 👑

so the tea is: this routine issues a fabric registration login for a vport. periodt. 🔥

⚠️ important prerequisite, no skipping: an active ndlp node with Fabric_DID must already exist for this vport. if it doesn't? that's a you problem, not a this-function problem. 💀

here's the cute part — it doesn't do the thing itself, it delegates, and it does so via two mailbox commands to carry out the fabric registration login through the HBA firmware:

  1. the first mailbox command asks the HBA to perform link configuration for the vport 🎀
  2. the second mailbox command asks the HBA to perform the actual fabric registration login with the vport ✨

and then the receipts (return codes):

  • 0 — successfully issued fabric registration login for vport. slay. 👑
  • -ENXIO — failed to issue fabric registration login for vport. 😭 not slay.
