Later, the > flow ID is used for flow operations (query, destroy, dump). > > The testpmd application allows to manage flow rules with its IDs. > The flow ID is known only when the flow is created. > In order to prepare a complete sequence of testpmd commands to > copy/paste, the flow IDs must be predictable. > > Allow the user to provide an assigned ID. > > Example: > testpmd> flow create 0 ingress user_id 0x1234 pattern eth / end actions > count / drop / end > Flow rule #0 created, user-id 0x1234 > > testpmd> flow query 0 0x1234 count user_id > > testpmd> flow dump 0 user_id rule 0x1234 > > testpmd> flow destroy 0 rule 0x1234 user_id > Flow rule #0 destroyed, user-id 0x1234 > > Here, "user_id" is a flag that signifies the "rule" ID is the user-id. > > The motivation is from OVS. OVS dumps its "rte_flow_create" calls to the > log in testpmd commands syntax. As the flow ID testpmd would assign is > unkwon, it cannot log valid "flow destroy" commands. > > With this enhancement, valid testpmd commands can be created in a > log to copy/paste to testpmd. > The application's flows sequence can then be played back in > testpmd, to enable enhanced dpdk debug capabilities of the > applications's flows in a controlled environment of testpmd > rather than a dynamic, more difficult to debug environment of the > application. > > Signed-off-by: Eli Britstein <el...@nvidia.com> > ---
