Subject: [dpdk-dev] [PATCH v8 3/4] app/testpmd: add dedicated flow command parsing routine
Date: Wed, 20 Oct 2021 18:14:56 +0300	[thread overview]
Message-ID: <20211020151457.17577-4-viacheslavo@nvidia.com> (raw)
In-Reply-To: <20211020151457.17577-1-viacheslavo@nvidia.com>

From: Gregory Etelson <getelson@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.
