> Flow contains the following information: port id, attributes, patterns and

> The function rte_flow_print prints all above information.

> It can be used for debugging purposes to validate the behavior of different

> Example: running testpmd with the following flow create:

> pattern eth src is 52:54:00:15:b1:b1 dst is 24:8A:07:8D:AE:C6 / end actions
> of_push_vlan ethertype 0x8100 / of_set_vlan_vid vlan_vid 0x888 /
> of_set_vlan_pcp vlan_pcp 7 / port_id id 0 / end Will result in this output:
