✨ NAME ✨

zfcp_fc_test_link — the lightweight link test procedure, no cap. It's the low-effort, high-reward vibe check for a link 💖

---

🦋 SYNOPSIS 🦋

void zfcp_fc_test_link (struct zfcp_port *port );

That's it. That's the whole signature. Void return, one arg, iconic behavior 👑

---

🌸 ARGUMENTS 🌸

• port — the port to be tested. Like, this is the port we're checking on. Give it a little look, bestie 🫶

---

🧚 DESCRIPTION 🧚

Okay so here's the tea: this function tests the status of a link to a remote port using the ELS command ADISC. That's the whole mission statement, periodt.

And if there's a problem with the remote port? Not me being dramatic but — error recovery steps will be triggered. So like, it's not just a cute little check, it actually does something when things go sideways 😭🔥

Heads up bestie: this isn't just informational. It's a real test that can kick off error recovery. Lowkey important, highkey useful 💅
