_base_build...len_sge_ieee(9)

okay so bestie, welcome to the _base_build...len_sge_ieee(9) page from the Kernel API Manual 💅✨ this one is short, sweet, and lowkey iconic: it's the helper that builds a zero length sg entry for IEEE format, and it's giving guardrail energy for the IOC hardware 🫶

---

✨ NAME ✨

_base_build_zero_len_sge_ieee — build zero length sg entry for IEEE format 💖

---

🌸 SYNOPSIS 🌸

the signature goes like this, bestie:

void _base_build_zero_len_sge_ieee (struct MPT3SAS_ADAPTER *ioc , void
*paddr );

---

🎀 ARGUMENTS 🎀

• ioc — per adapter object 🫶
• paddr — virtual address for SGE ✨

---

🦋 DESCRIPTION 🦋

Create a zero length scatter gather entry to insure the IOCs hardware has something to use if the target device goes brain dead and tries to send data even when none is asked for. 😭💀 that's it. that's the whole vibe. periodt.
