Test 854 "tunnel_push_pop - action" showed problems in revalidation for L3 protocol support in its L3 GRE test. L3 packets (that is, packets without an Ethernet header but only some L3 protocol such as IPv4 or IPv6) have an Ethernet type that is kept in the dl_type member of the flow, and the flows that they pass through can cause L3 and L4 fields to be matched. However, the translation process incorrectly forced the dl_type to be wildcarded, which caused a contradiction since it's not possible to match on L3 and L4 fields if the dl_type is not known, and the code in odp_flow_key_to_flow() and related functions therefore rejected these flows at revalidation time. This commit fixes the problem by treating dl_type the same for L2 and L3 flows in translation. It also makes odp_flow_key_to_flow__() copy the Ethernet type that comes from a packet_type field into dl_type, which is the expected behavior. The actual error that this fixes is only visible after applying an upcoming commit that improves logging for bad datapath flows.
