rtu_stat cannot change type of MAC entry (static/dynamic)
When an entry in the Filtering data base exists (either through dynamic learning or "rtu_stat add" command), its type cannot be changed anymore.
For example, try executing
1. add dynamic entry, assigning MAC 00:00:00:11:11:11 to port 2
rtu_stat add 00:00:00:11:11:11 2 1
2. modify the entry, changing the port and the type
rtu_stat add 00:00:00:11:11:11 1 0
the result is: the port is updated correctly, the type not.
