ppe_rss_hash_config_set(9)

💅 ppe_rss_hash_config_set(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual — it's ppe_rss_hash_config_set(9), and it's giving "niche but iconic" energy. ngl it's short, but every word ate. let's get into it 🎀

---

✨ NAME ✨

ppe_rss_hash_config_set — like, the whole vibe of this function is "configure the PPE hash settings for the packet received" 🌸 that's it, that's the job, and it does it slayfully.

---

🦋 SYNOPSIS 🦋

int ppe_rss_hash_config_set (struct ppe_device *ppe_dev , int mode ,
struct ppe_rss_hash_cfg cfg );

so it returns an int, takes a struct ppe_device *ppe_dev, an int mode, and a struct ppe_rss_hash_cfg cfg — copy that exactly, no cap, don't be out here renaming things 🙈

---

💖 ARGUMENTS 💖

• ppe_dev — the PPE device. yes, THE device. your main character 🫶
• mode — this is where you tell it to configure the RSS hash for the packet type IPv4 and IPv6. pick your fighter (or, like, both).
• cfg — the RSS hash configuration itself. the ~details~ ✨

---

🌈 DESCRIPTION 🌈

so basically: PPE RSS hash settings are configured for the packet type IPv4 and IPv6. that's literally the whole description bestie, it's a short king and we respect it 👑

---

⭐ RETURN ⭐

• 0 on success 💚
• a negative error code on failure 😭 (so like, if you see a negative number, it did not slay)

lowkey reminder: keep the args exactly as they're written, int mode and struct ppe_rss_hash_cfg cfg by value, no sneaky pointer-swapping 💅
