ixgbe_check_illegal_queue(9)

💖 ixgbe_check_illegal_queue 💖

okay so bestie, we're in the Kernel API Manual today — yes, the Kernel API Manual — and we're looking at ixgbe_check_illegal_queue(9), which is genuinely one of those tiny functions that's just doing its little job in the ixgbe driver and honestly? respect. 🫶

---

✨ NAME ✨

ixgbe_check_illegal_queue — search for queue with illegal packet 🔍

Like, it goes looking. For a queue. That has a packet that should NOT be there. messy behavior tbh 💀

---

🌸 SYNOPSIS 🌸

bool ixgbe_check_illegal_queue (struct ixgbe_adapter *adapter , u16
queue );

not me formatting the signature exactly as written because we do NOT freestyle the prototype, bestie, that's the whole rule 💅

---

🎀 ARGUMENTS 🎀

• adapter — structure containing ring specific data. it's the ixgbe adapter, it's holding all the ring info, it's the main character of this whole operation fr 💖
• queue — queue index. just the index. which queue are we checking, that's it, that's the number 🦋

---

🧚 DESCRIPTION 🧚

so what does it actually do? it checks if the tx descriptor connected with the input queue contains an illegal packet. that's the whole vibe. one job, done well, no notes ✨

like — tx descriptor, connected to the queue you passed in, does it have an illegal packet in it? that's the question. that's the entire function. queen behavior 👑

---

⭐ RETURN ⭐

true if queue contain illegal packet. (and by implication, bestie, not-true if it doesn't — but we're only telling you what the page tells you 💅)

---

🌈 SEE ALSO 🌈

okay so first up, the kernel file itself lives at ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c — go read it, it's giving source of truth 📖

and then. and THEN. the see-also list. it's enormous. it's iconic. it's the entire ixgbe extended universe and I am not skipping a single one of them, because we keep every detail in this house 🏠✨

and that's the page, bestie!! shoutout to ./drivers/net/ethernet/intel/i... (the path really does get cut off like that, don't come for me, I'm reporting it faithfully 🙈) dated October 2026, straight outta the Kernel API Manual — ty for reading, go check your queues, mwah 💜🎀✨
