qla24xx_detect_sfp(9)

💅 qla24xx_detect_sfp — kernel API manual, bestie edition ✨

okay so this is qla24xx_detect_sfp(9), straight out of the Kernel API Manual — yes the section 9 girlies are thriving today 🎀

---

✨ NAME ✨

qla24xx_detect_sfp — (the original leaves this space blank, and honestly? she's mysterious like that 🙈 no description given, that's just the vibe)

---

🌸 SYNOPSIS 🌸

int qla24xx_detect_sfp (scsi_qla_host_t *vha );

---

🦋 ARGUMENTS 🦋

• vha — the adapter state pointer 💖 like, the whole state of your adapter, handed to you on a platter.

---

👑 DESCRIPTION 👑

so this function comes back with an int, and the number it hands you is literally telling you which firmware settings to go with. here's the tea ☕:

• 0 — configure firmware to use short-range settings 💫 which means normal buffer-to-buffer credits. nothing extra, nothing dramatic, just the standard loadout.
• 1 — configure firmware to use long-range settings 🔥 and for this one, extra buffer-to-buffer credits should be allocated, with ha->lr_distance holding the distance settings — pulled from NVRAM or from the SFP (if supported 👀).

ngl, remember which branch does what — 0 = short range + normal credits, 1 = long range + extra credits + ha->lr_distance. no cap, that's the whole point of the function 💅
