I think for now it's okay to set the device into promiscuous mode and
enable the flag which checks for bad FCS... we can still implement the
filter modes later (and I think it should work on all supported
transceivers (except that SoftMAC/HardMAC thing)).

One point to promiscuous mode, currently we have a checking for if a
phy is in promiscuous mode on ifup and it would forbid to ifup a node
interface if the phy is in promiscuous mode (because of the missing
automatic acknowledgement). I see there is a need to turn the phy into
promiscuous mode during runtime... so we need somehow make sure the
constraints are still valid here. Maybe we even forbid multiple devs
on a phy if the transceiver/driver/firmware is poor and this is
currently all transceivers (except hwsim? But that doesn't use any ack
handling anyway).

yes, why not.

I need to admit, Stefan is the "Thanks, applied." hero here and he
should answer this question.
