When transmitting a packet via a mac802154 driver that can sleep in its transmit function, mac802154 defers the call to the driver's transmit function to a per-device workqueue. However, mac802154 uses a single global work_struct for this, which means that if you have more than one registered mac802154 interface in the system, and you transmit on more than one of them at the same time, you'll very easily cause memory corruption. This patch moves the deferred transmit processing state from global variables to struct ieee802154_local, and this seems to fix the memory corruption issue.
