The symptoms are that the interface can associate and even receive DHCP address, but after that all transmitted packets are lost. Any communication attempt results in ARP requests that are not seen by other devices on the network. Reverting this commit resolves the problem. I will be able to test patches tomorrow, please send them to me. If we are not able to resolve that before start of the stabweek which is this Monday, I'd like to get this reverted from main. -- Gleb Smirnoff
