mac802154_flush_list(9)

🌸 NAME 🌸

okay bestie, this is mac802154_flush_list(9) from the Kernel API Manual, and it's giving “free queued RX frames on @list” ✨ literally that's the whole name, no cap 💅

✨ SYNOPSIS ✨

the signature is lowkey simple:

void mac802154_flush_list (struct list_head *list , struct
       ieee802154_sub_if_data *sdata );

🎀 ARGUMENTS 🎀

• list — it's rx_beacon_list or rx_mac_cmd_list, bestie 🫶 pick your queue.
• sdata — only free frames received on this interface, or NULL for all. yep, NULL means “do the whole thing” 😌

💅 DESCRIPTION 💅

okay so here's the tea ☕: each frame pins the net_device it was received on (via netdev_hold), so you gotta release that reference as the frame is dropped. no leaving refs hanging, periodt 💖

⚠️ important vibe check: the caller must hold local->rx_lock. not optional, bestie — fr fr 🔒
