💅 mac802154_flush_queued_pkts(9) 💅

okay bestie so you found yourself in the Kernel API Manual for mac802154_flush_queued_pkts(9) and honestly? iconic of you. let's get into it 🎀

---

✨ NAME ✨

mac802154_flush_queued_pkts — drop queued RX work referencing @sdata 🗑️✨

---

🌸 SYNOPSIS 🌸

void mac802154_flush_queued_pkts (struct ieee802154_local *local ,
struct ieee802154_sub_if_data *sdata );

like, two args, void return, no drama. slay. 💅

---

🦋 ARGUMENTS 🦋

• local — the mac802154 device 🫶 this is the whole device vibe
• sdata — the interface being removed 😭 she's leaving, we're cleaning up after her

---

🔥 DESCRIPTION 🔥

okay so the workers dereference the queued frame's interface directly (via mac_pkt->sdata) or through skb->dev in mac802154_process_beacon. no cap, that's the whole reason this function exists.

so what we're doing here: drop the not-yet-started entries belonging to sdata before it gets unregistered, so their netdev reference is released. ✨

and bestie, listen — an entry that's already been dequeued by a running worker keeps its own reference until the worker completes, which unregister_netdevice then waits out. the way that's literally the whole safety story. main character energy from unregister_netdevice fr fr. 👑
