vagrant uses incorrect name of network interface for bridged interface

[aston-r]

Dear Developers,

This is continuation of bug that I reported in #7858 . I have updated to vagrant 1.8.7 and still had the same issue:

As you can see vagrant uses vlan(eth0.1), while it should use eth1.

> ip -o -0 addr | grep -v LOOPBACK | awk '{print $2}'
eth0:
eth1:
eth0.1@eth0:

> ls -l /etc/sysconfig/network-scripts/ifcfg-eth0.1*

-rw------- 1 vinod-990 devels 149 Nov 10 12:55 /etc/sysconfig/network-scripts/ifcfg-eth0.1@eth0

> cat /etc/sysconfig/network-scripts/ifcfg-eth0.1@eth0 
#VAGRANT-BEGIN

Let me know if you need more info.
