lpfc_init_link(9)

💖 lpfc_init_link(9) — the "wake up bestie, we're bringing the link online" era 💖

okay so this is lpfc_init_link from section 9 of the Kernel API Manual, and honestly? she's a whole vibe. no preamble, we're going straight in. 🫶

---

✨ NAME ✨

lpfc_init_link — ngl this one's whole job is prepping a mailbox command for initialize link on a HBA. that's it, that's the gig. 💅

---

🌸 SYNOPSIS 🌸

void lpfc_init_link (struct lpfc_hba * phba , LPFC_MBOXQ_t * pmb ,
uint32_t topology , uint32_t linkspeed );

---

🎀 ARGUMENTS 🎀

• phba — pointer to the lpfc hba data structure. your main character HBA, fr fr.
• pmb — pointer to the driver internal queue element for the mailbox command. this is the lil envelope the command rides in ✉️
• topology — the link topology that the link is getting initialized to.
• linkspeed — the link speed that the link is getting initialized to. go fast or go home 🏎️

---

🦋 DESCRIPTION 🦋

so the initialize link mailbox command is literally the thing used to initialize the Fibre Channel link. iconic behavior. ✨

⚠️ important lore bestie: this command must follow a configure port command — the one that establishes the mode of operation. don't skip ahead, the order matters, no cap. 💀

and this routine's specific job is preparing that mailbox command for initializing link on a HBA, using the link topology and speed you passed in. lowkey simple, highkey essential. 👑
