Public bug reported:

Use case: many trunk ports each with many subports.
Problem: port list takes much time.
Reason: for each port trunk extension adds a DB call to retrieve subports mac addresses.
Solution: retrieve subports info once when having a full list of trunk ports and hence full list of subport IDs.
