In case of rzusb which have an at86rf230 it doesn't support these
registers. There is no support for promiscuous mode. It's then a
broken behaviour when somebody sets this in rzusb.
Anyway rzusb isn't currently supported and I just want to leave a note
here. It's fine for me. Something for later to fix it in driver or
firmware handling.
