ppe_queue_u...set_hash_set(9)

🌸 ppe_queue_u...set_hash_set(9) — NAME 🌸

okay bestie, welcome to the Kernel API Manual, the literal group chat of kernel documentation 💅 and today's main character is ppe_queue_ucast_offset_hash_set — she sets the PPE unicast queue offset based on a hash. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

like, here's her whole signature, copy it exactly please, no cap:

int ppe_queue_ucast_offset_hash_set (struct ppe_device *ppe_dev , int
profile_id , int rss_hash , int queue_offset );

she takes four things and gives you back an int. she's lowkey simple like that 🎀

---

🍓 ARGUMENTS 🍓

the four besties she needs to function:

• ppe_dev — the PPE device, obviously. your whole fave hardware situation 👑
• profile_id — the Profile ID. yes it's just a profile id, she's not gonna explain further 💀
• rss_hash — the packet hash value that gets used to set the queue offset. this is the moment, this is the hash 🧚
• queue_offset — the queue offset, used for calculating the destination queue ID. math girlie behavior fr fr 🌈

---

💜 DESCRIPTION 💜

so the tea is: the PPE unicast queue offset gets configured based on the RSS hash value. that's the entire plot 😭 she's not doing a whole monologue, she's just setting that offset off the hash and minding her business. iconic, honestly. ate and left no crumbs 🫶

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code on failure 😭 (yes negative, don't @ me)

ngl that's the whole page — she's short, she's sweet, she sets one offset. periodt 💅

anyway bestie, that's a wrap 🎀 this lil gem comes from ./drivers/net/ethernet/qualcom... and she's stamped October 2026, so go forth and configure your queue offsets responsibly, mwah 💖✨
