[UPDATE]

Update infos from comments on answer: Mean while I have another problem after configuring bonding for interfaces. Eth1 is the usb-modem, which becomes the Ethernet interface with usb_modeswitch. When this interface is not bonding - it becomes 'up' with ip address (common situation). When bonding - eth1 is down, however the eth0 is up. I believe, the problem comes from usb dongle router.

Definitely, this issue happens right after I disable dhcp on eth1. echo "denyinterfaces eth0 eth1" >> /etc/dhcpcd.conf
