Sprint:VOLTHA 2.10 - Sprint 8
Remove restriction that flows have to be replicated for all the 8 pbits when replication is enabled.
As per DT FTTB Subscriber Traffic Tech Profile we see that one of the pbits (pbit7) does not map to any gem port and hence the replication count of the ONOS flow on the hardware device is just 7 (for pbits 0 to 6) and not 8 (i.e., pbits 0 to 7). So we need to remove such a restriction in openolt agent code.
Below is the TechProfile that I was describing before. Note that pbit7 does not map to any gem port
