Description of problem:
After setting up a gre tunnel to mirror traffic between instances running on separate compute nodes, the compute node reboots unexpectedly about 10 minutes later.

Version-Release number of selected component (if applicable):
openvswitch-2.4.0-1.el7.x86_64

How reproducible:
Has happened on 2 compute nodes in the same environment

Steps to Reproduce:
1. Use the following commands to set up a gre tunnel
2. Observe reboot

ovs-vsctl add-port br-monitor gre1 -- set interface gre1 type=gre options:remote_ip=<ip> options:key=2000

ovs-vsctl -- add Bridge br-int mirrors @m -- --id=@host1 get Port qvo6b8906b1-50 -- --id=@vasi get Port gre1 -- --id=@m create Mirror name=mirror select-src-port=@host1 select-dst-port=@host1 output-port=@vasi

Actual results:
Compute node reboots shortly (about 10 minutes) after applying this

Expected results:
No reboot, traffic is mirrored between hosts
