Current version is mapping sensitivity configuration into Prism2
cnfSystemScale with those three options. However, this does not really
control what you would like to set with sensitivity threshold. Some of
the BBP control registers might be more helpful, but I have not
experimented with that kind of configuration.

That looks like a multicast frame from an (pseudo?) adhoc network..
Since the destination address is multicast, it will be delivered to the
driver in Host AP mode. That kernel message should probably be just
removed and those frames could then be silently dropped..
