💅 lpfc_link_reset — Issue link reset

ok so before we even start: this is page lpfc_link_reset(9) out of the Kernel API Manual, section 9, bestie. kernel-section-nine. that's the "functions you call inside the kernel" section, not the "type this in your shell" section. iykyk 🧚

✨ NAME ✨

lpfc_link_reset — Issue link reset 🎀

no seriously that's the whole name. it resets the link. that's the vibe.

---

✨ SYNOPSIS ✨

int lpfc_link_reset (struct lpfc_vport *vport );

one function, one argument, returns an int. clean. minimal. she ate. 👑

---

✨ ARGUMENTS ✨

• vport — pointer to a virtual N_Port data structure. that's your vport bestie 🫶 it's the virtual port you're about to make do a whole link reset. treat her with respect.

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ — this routine performs a link reset by sending an INIT_LINK mailbox command. literally that's the move. you call it, it fires off INIT_LINK to the hardware, and the link gets reset. slay. 💅

and then there's the SLI-3 adapter special case, because of course there's a special case: for SLI-3 adapter, the link attention interrupt is enabled before issuing the INIT_LINK mailbox command. so order matters here — interrupt goes on, then the mailbox command goes out. don't flip that. 🔥

Return code, and this is important so read it twice:

• 0 — Link reset initiated successfully ✅
• 1 — Failed to initiate link reset 😭

yes, 0 means good and 1 means bad. classic. not me getting that backwards at 3am one time 🙈

ngl the return values are the whole story here — 0 is "we started it", 1 is "we did not start it". it says "initiated", not "finished". don't @ me, that's what the page says. ⭐
