From: Gregory Etelson <getel...@nvidia.com>
testpmd flow creation is constructed from these procedures:
1. receive string with flow rule description;
2. parse input string and build flow parameters: port_id value,
flow attributes, items array, actions array;
3. create a flow rule from flow rule parameters.
Flow rule creation procedures are built as a pipeline. A new
procedure starts immediately after successful predecessor completion.
Due to this we have no dedicated routines providing intermediate
results for step 1-3 above.
The patch adds `flow_parse()` function call. It parses input string
and provides a caller with parsed data. This is a preparation step
for introducing flex item command processing.
