The same applies to receiving. The RX queue is also dropped on switch

advertisement, sent to 33:33:00:00:00:01). I have no idea where the
packet is dropped; from my somewhat limited understanding of 802.11, I'd
expect the frames to be treated like broadcast frames by the AP, so it'd
be the receiver dropping them in the MAC filter.
The actual switch from DMA to PIO mode completely reinitializes
the hardware and drops all queues.
