Before this commit the dev_flow handle structure was reused in each new flow_verbs_translate() call, however the dev_flow->hash_fields variable was not reset before each call. As a result hash_fields from previous calls remained present in the current flow which lead to invalid combinations (e.g. simultaneous IPv4 and IPv6 specs). This scenario happens for example in the next flows sequence, when running in verbs mode (dv_flow_en=0). flow create 0 ingress group 0 pattern eth / ipv4 / end flow create 0 ingress group 0 pattern eth / ipv6 / end The fix is to reset dev_flow->hash_fields in flow_verbs_prepare().
