Port Filter

This module contains the impairment port flow filter commands.

There are 2 register copies used to configure the filters:

1. Shadow-copy (type value = 0), temporary copy configured by sever. Values stored in shadow-copy have no immediate effect on the flow filters. PEF_APPLY will pass the values from the shadow-copy to the working-copy.

2. Working-copy (type value = 1), reflects what is currently used for filtering in the FPGA. Working-copy cannot be written directly. Only shadow-copy allows direct write.

3. All set actions are performed on shadow-copy ONLY.

4. Only when PEF_APPLY is called, working-copy and FPGA are updated with values from the shadow-copy.

Note

Flow filter is only applicable to flow ID from 1 to 7. You cannot place a filter on flow 0.
