Changing the MAC address on the lagg interface does not get retained after lagg port delete operation.
How to reproduce:
-> Create a lagg interface
-> Add 2 ports to a lagg interface
-> Set the NEW MAC address on the lagg interface, which in-turn change the MAC of the 2 physical ports.
-> Remove a lagg port from the lagg interface. (It should be the first interface of LAGG / Master port)
-> The NEWLY ADDED MAC address will be lost, the lagg interface will have the other members physical interface MAC interface.
-> At first place, why the MAC change is allowed on the lagg interface.
-> If allowed then the MAC shall be the generic MAC, that shall not be affinity to a phyiscal port. Hence add / delete port operations on the lagg interface should not affect the lagg interface MAC address (Unless all the ports were deleted).
