Hi All, I am trying to understand how selection method dp_hash is used in recirc action in datapath. With dp_hash in use, ovs action OVS_ACTION_ATTR_HASH is triggered which invokes execute_hash(...) to calculate ovs flow hash based on the hash basis received as netlink attribute and populates key->ovs_flow_hash.
But during subsequent calls to execute_recirc(...)->clone_execute(...)->ovs_dp_process_packet(...)->ovs_flow_tbl_lookup_stats(...), skb_hash is used instead of DP populated hash in key->ovs_flow_hash to look up the flow in ovs_flow_tbl_lookup_stats(...). If someone can help me understand why hash in key->ovs_flow_hash is not used here if it is available and is non zero that will be great help. Thanks, Jai
