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
