[PATCH] Test 802.1Q vlan of nic

[Amos Kong <akong@redhat.com>]

Test 802.1Q vlan of nic, config it by vconfig command.
1) Create two VMs
2) Setup guests in different vlan by vconfig and test communication by ping
   using hard-coded ip address
3) Setup guests in same vlan and test communication by ping
4) Recover the vlan config
