t4_read_rss_key(9)

💅 t4_read_rss_key(9) — hey bestie, welcome to the page 💅

okay so this is the kernel API manual page for t4_read_rss_key, and yes it's a short one but that does NOT mean it's not iconic. sit down, hydrate, let's get into it 🫶

---

✨ NAME ✨

t4_read_rss_key — read the global RSS key 💖

like, that's it. that's the whole vibe. but keep reading, bestie, because the details matter.

---

🦋 SYNOPSIS 🦋

void t4_read_rss_key (struct adapter *adap , u32 *key , bool sleep_ok );

no cap, that's the exact signature — spaces and all. copy it character for character or don't come crying to me 😭

---

🎀 ARGUMENTS 🎀

• adap — the adapter. it's giving "the hardware thing we're talking to". main character energy fr.
• key — a 10-entry array holding the 320-bit RSS key. so that's ten u32s, all of them filled in with the tea 🔥
• sleep_ok — if true, we may sleep while awaiting command completion 😴 like, we're allowed to nap. if it's not true, bestie, do NOT nap. periodt.

---

🌸 DESCRIPTION 🌸

It reads the global 320-bit RSS key.

the way that's literally the entire description 😭 short and sweet, an absolute queen. the key lands in the key array you passed in, and the sleeping situation is entirely up to what you set sleep_ok to. slay.

ngl it's a tiny function with a big job — every long legend has an origin story 💅

look at that roster 😭 every single one of them tagged (9) and accounted for. iykyk. not a single name dropped, not a single one merged. we do NOT do that here 💀✨

that's the whole page, bestie — short, sweet, and every last reference intact 🎀

this lil cutie comes to you from the source/version <rainbow>./drivers/net/ethernet/chelsio...</rainbow> and it's dated October 2026 — so like, future girl summer energy ⭐ mark your calendars, screenshot it, put it on the fridge 💜

bye bestie, go read a global 320-bit RSS key responsibly 🦋💖
