💖 ixgbe_cache_ring_rss(9) — a kernel API manual moment ✨

okay so bestie, we're in the Linux Kernel API Manual today, and this page is literally about ixgbe_cache_ring_rss — the little function that handles descriptor ring to register mapping for RSS. iykyk. let's get into it 🎀

---

🌸 NAME 🌸

ixgbe_cache_ring_rss — Descriptor ring to register mapping for RSS 💅

---

✨ SYNOPSIS ✨

bool ixgbe_cache_ring_rss (struct ixgbe_adapter *adapter );

like, it returns a bool, takes one pointer, and it's giving "i do one job and i do it well" energy. periodt. 👑

---

🫶 ARGUMENTS 🫶

• adapter — the board private structure you're initializing. that's it. that's the whole vibe. hand it over and let her cook 🍓

---

🌈 DESCRIPTION 🌈

So here's the tea ☕ — ixgbe_cache_ring_rss caches the descriptor ring offsets for RSS to the assigned rings. literally just that. it's the "write it down so nobody has to redo the math later" of the queue-setup world, and honestly? iconic. 💖

no cap, it's a small one, but it's a load-bearing small one — the offsets gotta land on the right rings or the whole RSS situation gets weird. slay. 🦋

friendly reminder: this is the RSS-flavoured member of the ixgbe_cache_ring_* family — the DCB, SRIOV and _register siblings up there are the other flavors. know the difference, bestie, iykyk 🤞
