💅 lpfc_sli4_unrecoverable_port(9)

okay so bestie, this little page comes from the Kernel API Manual, and it's all about lpfc_sli4_unrecoverable_port — a tiny check for the ERR and RN bits in portstat_reg. lowkey specific, highkey useful. ✨

🌸 NAME 🌸

lpfc_sli4_unrecoverable_port — check ERR and RN bits in portstat_reg.

---

🦋 SYNOPSIS 🦋

bool lpfc_sli4_unrecoverable_port (struct lpfc_register *portstat_reg );

---

🎀 ARGUMENTS 🎀

• portstat_reg — a portstat_reg pointer containing the portstat_reg contents. Like, it's the pointer to the register snapshot you're inspecting, bestie.

---

✨ DESCRIPTION ✨

Use only for SLI4 interface type-2 or later. fr fr, don't use it for anything earlier.

If ERR is set && RN is 0, then the port is deemed unrecoverable. That's the whole vibe check: ERR says something is up, RN is not set, and the port gets the "yeah, that's unrecoverable" label. 💀

---

🔥 RETURN 🔥

• true — ERR && !RN
• false — otherwise
