wx_cache_ring_rss(9)

💖 wx_cache_ring_rss(9) — the Kernel API Manual page, but make it make sense 💖

okay so bestie, bestie. sit down. we're doing kernel networking today and honestly? this one is a lil snack. it's wx_cache_ring_rss(9), from the Kernel API Manual, section 9 (that's the kernel-API section, iykyk 🧚). it's short, it's sweet, it does exactly one vibe and does it iconically.

✨ NAME ✨

wx_cache_ring_rss — the descriptor-ring-to-register-mapping-for-RSS situation. yes that's the whole name. no cap. 🎀

---

✨ SYNOPSIS ✨

void wx_cache_ring_rss (struct wx *wx );

that's it. that's the whole call. no return value — it's a void, so don't be out here trying to if it, bestie, it's giving nothing to check 💅

---

✨ ARGUMENTS ✨

• wx — the board private structure you're initializing. that's the one. that's your girl. she's a struct wx * and she's a main character.

---

✨ DESCRIPTION ✨

so what does it do? it caches those descriptor ring offsets. for RSS, ATR, FCoE, and SR-IOV. all four. in one go. efficient queen 🫶

that's genuinely the whole description — it's a cache-it-now-so-you-don't-hunt-for-it-later type beat, and honestly we respect a function that knows exactly what it is.

real talk: nothing here is dangerous, nothing is deprecated, there are no flags, no exit statuses, no signals, no environment variables. it's a void function with one argument and a cutesy cache. lowkey the easiest page in the book 🔥

and that's the page!! 🌈⭐ this gem was brought to you by the source path ./drivers/net/ethernet/wangxun... and dated October 2026, and the footer had one more thing to say: wx_cache_ring_rss(9). mwah 💋 periodt. 🎀✨💖
