Bug Description
Brought up the setup with the build ocata-master-294 on multi node setup.
While bringing up the vlan interface kernel is crashed. Because of that compute nodes got rebooted.
Steps to repro:
1. Create 2 VNs vn1 and vn2
2. Create a port called port1 for vn1 and launch vm for that port
3. Create a sub interface called sub-intf with vlan id 101 for port1 under vn2 network
4. Create a sub interface with the vlan 101 by the command sudo vconfig add eth0 101 inside vm.
5. Bring up the sub interface on vm using the command sudo ifconfig eth0.101 up.
While performing step5 kernel is crashed.
