Re: [PATCH 2/2][RFC] mac80211_hwsim: Report radio addresses in NEW_RADIO/GET_RADIO

radios are directly created by there internal ID, which is only
increased for new radios and definitely not reassigned.

But I would be happy, if this were possible, since it would make some
simulation related stuff easier (currently we need to unload and load
the hwsim module over and over again for every run).

Ahh, you are right.  But you can specify the wiphy name, and then you
can use that to query the debugfs to find the MAC addr, and then sync
your user-space with that info.

It should also be easy enough to specify the MAC address when creating
the radio.

And, you should be able to create virtual STA, AP, etc, with any
specified
MAC address, so the MAC of the radio really should not matter much?

That is another problem ... this won't work currently, since the frame
delivery compares the receiver address with the permanent MAC addresses
of all hwsim phys. I work as an idle task on patch, which makes this
lookup (currently implemented as linear search) as a hashmap mapping an
MAC to a wiphy struct , including scenarios with differing MAC addresses
of vifs.

Thanks,
Ben

kind regards
