Each running Docker container has a virtual network interface that
dhcpdtries to keep track of.dhcpdcan crash when dealing with a large number of interfaces and the device will then become unresponsive over the network.This change just configures
dhcpdto ignore all virtual network interfaces which resolves the issue.Related: raspberrypi/linux#4092
