The security groups RPC handler calls get_port_from_device individually for each device in a list it receives. Each one of these results in a separate SQL query for the security groups and port details. This becomes very inefficient as the number of devices on a single node increases. This patch adds logic to the RPC handler to see if the core plugin has a method to lookup all of the device IDs at once. If so, it uses that method, otherwise it continues as normal. The ML2 plugin is modified to include the batch function, which uses one SQL query regardless of the number of devices. Closes-Bug: #1374556 Change-Id: I15d19c22e8c44577db190309b6636a3251a9c66a
