Can't explain better, but I found root cause.

So, full steps to reproduce:

1) sudo service NetworkManager stop
2) sudo wpa_supplicant -c /etc/wpa_supplicant/wired.conf -i eth1 -D wired
3) sudo dhclient eth1
4) see in output "ls: cannot access '/run/systemd/resolved.conf.d/isc-dhcp-v6-***.conf': No such file or directory"
5) check ifconfig that only IPv4 address was received

Work-around: Disable IPv6 for Ethernet
