lpfc_sli4_bs...oopback_mode(9)

💖 lpfc_sli4_bsg_diag_loopback_mode — from the Kernel API Manual, bestie 💖

okay so this page is lpfc_sli4_bsg_diag_loopback_mode(9) and it lives in the Kernel API Manual — yes, that manual, the one that's giving "I know things" energy. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

lpfc_sli4_bsg_diag_loopback_mode — the one that processes an sli4 bsg vendor command. that's literally her whole job. 🎀

---

🦋 SYNOPSIS 🦋

int lpfc_sli4_bsg_diag_loopback_mode (struct lpfc_hba *phba , struct
bsg_job *job );

like, yes, it returns an int. we love a classic. ✨

---

🌸 ARGUMENTS 🌸

• phba — a pointer to the HBA context object. it's giving "here's the whole world, handle it" 👑
• job — this one is LPFC_BSG_VENDOR_DIAG_MODE. that's it, that's the arg. no cap. 💅

---

🔥 DESCRIPTION 🔥

so what does she actually do? this function is the one responsible for placing an sli4 port into diagnostic loopback mode, so you can go ahead and perform a diagnostic loopback test. that's the whole vibe. main character energy for real — she doesn't do anything else, she does this, and she does it well. 🫶

sign-off time: this icon lives in ./drivers/scsi/lpfc, dated October 2026, and yeah — the title got cut off in the header/footer as lpfc_sli4_bs...oopback_mode(9), but we both know who she is. slay, go run your diagnostic loopback test, and hydrate 💜🦋🌸
