Browse Source 
Signed-off-by: Neetha John <nejo@microsoft.com>

Why I did it
ECN parameters need to be updated for storage backend

How I did it
Included the check for storage backend devices to update qos configs

How to verify it
Verified that the new ecn settings are applied on storage backend device.
Verified that the old ecn settings are applied for storage frontend, non storage frontend/backend devices
