[dpdk-dev] [PATCH v4 0/3] support single flow dump

[Haifei Luo <haifeil@nvidia.com>]

Dump internal representation information of all flows is supported.
It is useful to dump one flow. To implement this requirement,
add this CLI to dump one rule: flow dump PORT rule ID
      and the CLI to dump all: flow dump PORT all
Examples:
    testpmd> flow dump 0 all
    testpmd> flow dump 0 rule 0
The first 0 is for port. The second one is for rule id.

For RTE API, add one arg rte_flow in rte_flow_dev_dump.
If rte_flow is null, it will dump information for all flows.
Otherwise, it will dump one.
Accordingly, add this arg in related dev_dump and driver APIs.

V2: fix comments about rte API. V1 has one API rte_flow_dump,
remove it and update rte_flow_dev_dump by adding one arg rte_flow.

V3: split into two series. One is for ethdev/testpmd/doc, the other is
for drivers.

V4: Fix comments. Remove "Flow dump" from features/default.ini and
features/mlx5.ini.
