[PATCH v13 5/6] doc: add AI-assisted patch review to contributing guide

[Stephen Hemminger <stephen@networkplumber.org>]

Add a new section to the contributing guide describing the
analyze-patch.py script which uses AI providers to review patches
against DPDK coding standards before submission to the mailing list.

The new section covers basic usage, provider selection, patch series
handling, LTS release review, and output format options. A note
clarifies that AI review supplements but does not replace human
review.

Also add a reference to the script in the new driver guide's
test tools checklist.

+AI-Assisted Patch Review
+------------------------
+
+Contributors may optionally use the ``devtools/analyze-patch.py`` script
+to get an AI-assisted review of patches before submitting them to the mailing list.
+The script checks patches against the DPDK coding standards and contribution
+guidelines documented in ``AGENTS.md``.
+
+The script supports multiple AI providers (Anthropic Claude, OpenAI ChatGPT,
+xAI Grok, Google Gemini).  An API key for the chosen provider must be set
+in the corresponding environment variable (see ``--list-providers``).
+
+Basic usage::
+
+   # Review a single patch (default provider: Anthropic Claude)
+   devtools/analyze-patch.py my-patch.patch
+
+   # Use a different provider
+   devtools/analyze-patch.py -p openai my-patch.patch
+
+   # Review for an LTS branch (enables stricter rules)
+   devtools/analyze-patch.py -r 24.11 my-patch.patch
+
+   # List available providers and their API key variables
+   devtools/analyze-patch.py --list-providers
+
+For a patch series in an mbox file, the ``--split-patches`` option reviews
+each patch individually::
+
+   devtools/analyze-patch.py --split-patches series.mbox
+
+   # Review only a range of patches
+   devtools/analyze-patch.py --split-patches --patch-range 1-5 series.mbox
+
+When reviewing for a Long Term Stable (LTS) release, use the ``-r`` option
+with the target version.  Any DPDK release with minor version ``.11``
+(e.g., 23.11, 24.11) is automatically recognized as LTS,
+and the script will enforce stricter rules: bug fixes only, no new features or APIs.
+
+Output can be formatted as plain text (default), Markdown, HTML, or JSON::
+
+   devtools/analyze-patch.py -f markdown -o review.md my-patch.patch
+
+The review guidelines in ``AGENTS.md`` focus on correctness bug detection
+and other DPDK-specific requirements. Commit message formatting and
+SPDX/copyright compliance are checked by ``checkpatches.sh`` and are
+not duplicated in the AI review.
+
+.. note::
+
+   Always verify AI suggestions before acting on them.
