I think a more proper fix is to remove the first argument of StartPacketInHandler and just get the reasons from the keys of c.packetInHandlers to avoid all the redundancy and inconsistency.

@wenyingd @hongliangl does the above way work?

I prefer this way.

yes, it looks better. updated
…disabled Currently, packetIn reason only supports 0 and 1. There is no more available packetIn reasons as traceflow and antreaPolicy use both. Multicast reuses packetIn reason with antreaPolicy, and uses a different register bit to indicate the real reason. There is no queue for packetIn reason 'PacketInReasonNP' if antreaPloicy is disabled. And multicast will not work then. This patch fixes antrea-io#3808 Signed-off-by: Bin Liu <biliu@vmware.com>
