Kishore Padmanabha a241760189 net/bnxt: identify duplicate flows
Conflict resolution feature allows rejection of flows based on
the previously added flows that conflict. For instance, a five
tuple flow is added and then you add a new flow with only 4 tuple
instead having same layer2 details then it will be rejected.
