💅 irdma_fragcnt_to_quanta_sq(9) 💅

okay so bestie, you're in the Kernel API Manual, section 9, and today's main character is irdma_fragcnt_to_quanta_sq(9) — say that five times fast, i dare you 😭

---

✨ NAME ✨

irdma_fragcnt_to_quanta_sq — literally does the math to figure out the quanta from the fragment count, and it's specifically for the SQ (send queue, iykyk) 🎀

---

🌸 SYNOPSIS 🌸

int irdma_fragcnt_to_quanta_sq (u32 frag_cnt , u16 *quanta );

that's it. that's the whole vibe. returns an int, takes two args. slay 💅

---

🦋 ARGUMENTS 🦋

• frag_cnt — the number of fragments, fr fr. that's the input, girl, that's what you're feeding it 🍓
• quanta — this bad boy is a pointer (u16 *), and it's where the quanta for frag_cnt ends up. output goes here, no cap ✨
