ieee802154_rx_irqsafe(9)

✨ ieee802154_rx_irqsafe — receive frame ✨

okay bestie, welcome to the ieee802154_rx_irqsafe(9) kernel API page 💖 this is the irq-safe girlie of the 802.15.4 receive world, and honestly she's iconic for a reason. let's get into it 🎀

---

🌸 SYNOPSIS 🌸

void ieee802154_rx_irqsafe (struct ieee802154_hw *hw , struct sk_buff
*skb , u8 lqi );

that's the whole signature, no cap 💅 three params, returns nothing, slays quietly.

---

🦋 ARGUMENTS 🦋

• hw — the hardware this frame came in on 🫶 like, which radio delivered it, bestie.
• skb — the buffer to receive. big note tho: after this call, it's owned by mac802154 😭 so don't you dare touch it after, that's their buffer now, periodt.
• lqi — link quality indicator 💀 a u8, just vibes about how good the link was.

---

🔥 DESCRIPTION 🔥

so basically this is like ieee802154_rx but the whole point is you can call it from IRQ context ⭐ because it internally defers the real work to a tasklet 🧚‍♀️ like, "not me doing this in interrupt context," — she hands it off and keeps it moving. main character energy fr fr.

ngl if you're in interrupt context and need to receive a frame, this is your girl. ieee802154_rx can't do that.
