Why can we not set the mcast rate for AP/STA interfaces?

From looking at 3.17 code, it appears we are only supposed to set the

mcast rate for mesh and IBSS interfaces?

What if I want to tell an AP or station to send broadcast/multicast at a higher than default rate?

Should this just be controlled by the normal 'iw setbitrates' logic?

Thanks,
Ben

On which 802.11 amendment (a/b/g/n/ac) and driver allows you setting mcast rate for mesh and IBSS interfaces?
Far as I know, some vendors send multicast traffic as unicast in order to reduce airtime.

I was just looking at the kernel code, I think it was linux/net/wireless/* where the device type is made. I didn't look farther to figure out what it would take to make this work with stations or APs.

Thanks,

Ok. I was asking because some routers allow changing basicrate speed but only on 802.11a/b/g, in AP mode, not on mesh/Ad-Hoc modes. Some non-mandatory feactures can be on code of one module but not implemented in the whole process.

Thanks.
