When SAI_ROUTE_ATTR_NEXT_HOP_ID = SAI_NULL_OBJECT_ID, packet is dropped. This allows user to change packet action from DROP to FORWARD using set API. Otherwise, the behavior transition from DROP to FORWARD is undefined.

@kcudnik , this PR give following error. Processing saiwred_8h.xml Can you help? |

| * When it is SAI_NULL_OBJECT_ID, then packet will be dropped. |

Just to confirm the understanding that NULL_OBJECT_ID can be set when packet action is set to TRAP before and the packet action will take precedence in that case. In other words, the packet will be dropped when packet action is one of the following: FORWARD, COPY, LOG, TRANSIT as mentioned in the comments.

Yes, that is the understanding. packet action will take precedence.

or its just cancel forward copy. So for LOG and COPY we still get a copy.

Jenkins, test this please |
… forward" (#138) This change breaks the latest test as the current SAI implementation doesn't support the mid-state that the route with packet action DROP is set with next hop ID and packet action FORWARD by two steps. The implementation also prevents removing the default route and create a new route instead. After the SAI implementation is fixed, this change will be re-introduced. ref: opencomputeproject/SAI#253
