Hi Ard,
Could we upgrade broadcast to promisc? The spec allows using a “wider” filter.
Eh, are you sure the hardware needs the promiscuous mode enabled to
receive broadcast frames?
Could we treat multicast the same way? So any non-unicast filter means promisc?
The MNP layer already takes care of that.

Move the handling of the promiscuous receive control to the SNP
ReceiveFilters() method where it belongs. Given that we do not
support multicast filtering, only minimal handling is required to
test the promiscuous bit and program the MAC accordingly. Any
multicast handling will be done by the MNP layer above it.
