Default rates for broadcast, multicast, and management frames?

ath10k firmware allows one to set fixed rates for broadcast, multicast, and management/beacon
frames. I think upstream firmware may not have full support, but the API is there in 10.1,
at least, and CT firmware has full support.
I think the defaults are 6Mbps, but not certain of that.
CT kernels have a patch that gives debugfs access to set this, and I am also
working on automatically decreasing the rate down to 1Mbps if user has specified
only /b legacy rates, etc.
Instead of using whatever the firmware chooses for defaults, I think it is
better if the driver explicitly set the rates as desired.
So, what are the suggested defaults for these rate types? Stick with 6Mbps for
/b/g and /a modes? Set to 1Mbps of /b mode? Different defaults for different
Also, at least some ucast/bcast frames may be turned into directed frames and
then it may use normal peer rate-ctrl logic, as far as I remember.
