RDMA device renames and node description

[Dennis Dalessandro <dennis.dalessandro@xxxxxxxxx>]

Was there any discussion on the upgrade scenario for existing 
deployments as far as device-rename changing node descriptions?

If someone is running an older version of rdma-core they are going to 
have a certain set of node descriptions for each node. This could be in 
logs, or configuration databases, who knows what. Now if they upgrade to 
a new version of rdma-core their node descriptions all automatically 
change out from under them by default.

Of course the admin could disable the rename prior to upgrade and as 
Leon pointed out previously the upgrade won't remove the disablement 
file. The problem is they would have to know to do that ahead of time.
