Description of problem:
Please incorporate the Nexus MD ML2 Plugin Solution for OSP9:
https://review.openstack.org/#/c/358817/

There exists a neutron process with both a Nexus replay thread and a config thread. These threads share the same ssh session. When they are talking to Nexus at the same time, I saw one thread closing the nexus ssh session before the other thread was complete resulting in unexpected errors.

Version-Release number of selected component (if applicable):

How reproducible:
Very much so with scale and replay configured

Steps to Reproduce:
1. Scale Ml2 Port traffic
2. Replay configured in ml2_conf_cisco.ini file (switch_heartbeat_time = 30)
3.

Actual results:


Expected results:
