QCA988X firmware crash when sending in monitor mode

[Ouri Lipner]

I’m aware of what the wiki says, but was under the impression this is outdated.
Recent firmware files have a raw mode capability, and there is also code in the driver to handle it.

Adding an AP alongside the monitor vdev is an interesting idea, thanks.
I’ll have to disable beacon send etc...

    To the best of my knowledge firmware does not support frame injection
    on monitor vdev. Therefore this is expected. Moreover this limitation
    is mentioned on ath10k wiki:
    https://wireless.wiki.kernel.org/en/users/drivers/ath10k

    You could probably hack up the driver to create and use AP or STA vdev
    alongside monitor vdev to use it's vdev_id for frame injection. I'm
    not aware of anyone trying that out so far though.
