bin/149351: [request] dhclient(8): DHCP can make one interface to have multiple IP addresses

[Jin Guojun]

This is not the issue for having multi-home interface. Typically, we can assigned a primary IP to xyz0, then set a few other different subnet IPs to xyz0:1, zyx0:2, etc. And interface xyz0 will work for multi-home NIC.

But in this case, the interface stop working -- the machine cannot reach to the network.

I will look into this further to see if I can got a solution or figure out what is the problem.
