wpa_supplicant - after updating kernel to 4.12, no traffic

[Yaroslav Isakov]

Hello! I found that after updating to 4.12 kernel, after rebooting my
dhcpcd cannot get an address. I'm using an option
"preassoc_mac_addr=2", and after I've commented it, problem was fixed.
I've bisected the kernel, and found that commit
https://github.com/torvalds/linux/commit/cd8966e75ed3c6b41a37047a904617bc44fa481f
is causing this. So, is it a kernel regression, or is wpa_supplicant
relying on kernel bug?
