Ah, you're probably right, perhaps we would have one vif but multiple
stas.

Sorry, my recollection of mac80211 code is waning, but can't we have
more than one vif as long as they are on the same channel?

Hi Jakub,
yep, you are right, but according to my understanding (please correct me if
it is wrong) current implementation supports just one interface in sta mode
(i.e. mvif->idx is always 0) so my patchset just fixes the issue highlighted
in the bugzilla since I do not know if the hw supports multiple concurrent vifs
in client mode. If so, I can extend the support to multiple client vifs if it is
a way to properly configure the rx filters to allow reception from multiple mac
addresses.
Regards,
Lorenzo
If mac80211 adds a vif with a different mac address respect to
the eeprom one, the device will not be able to connect to the ap
since the hw address has not been updated.
