This has been working for several years on 4.7 and earlier kernels, but when testing on 4.9 overnight, I notice that 'iw events' is not showing any input. 'strace' shows that it is waiting on recvmsg. If I start a second 'iw events' then it will get wifi events as expected. Are there any known issues in this area?
