Typically you inject frames via monitor vif in radiotap mode. This
doesn't imply anything about driver implementation.

It crashes soon after starting a lone monitor vdev but I recall it
worked as long as you run it alongside, e.g. an associated station
interface so you can try working around this problem. Or you can run
10.2.

Then Txing with monitor vdev_id will definitely crash all known
firmware binaries. Other vdev types need peer entries to be set up
before a frame can be sent with certain DA (otherwise it stays in the
queues indefinitely). Take a look at the offchannel worker in ath10k
as it may be useful if you want to get this running (at least to a
limited degree).

Also, with raw tx in ath10k you can probably try playing with mesh
because QoS Control is no longer stripped, right?
