## Patch 1/7: doc: detect ignored public headers

### Errors

**Variable `doc_dir` overwritten before read:**
In `lib/meson.build` at line 221, the variable `doc_dir` is referenced in the warning message,
but the loop iterates over `doc_dirs` (plural) with loop variable `d`.
The message should reference `d` instead of `doc_dir`.

```diff
-                warning('public header directory @0@ is not listed in @1@'.format(doc_dir,
+                warning('public header directory @0@ is not listed in @1@'.format(d,
                     doc_build_path))
```

### Warnings

**Script robustness:**
The `sed` script in `meson.build` assumes well-formed input and may silently produce incorrect results
if the doc files have malformed syntax.
Consider adding error handling or validation that the extracted lists are non-empty and plausible.

## Patch 7/7: doc: add missing headers to doxy-api-index.md

### Warnings

**RST definition list pattern:**
In `doc/api/doxy-api-index.md`, several sections use bullet lists where definition lists would be more appropriate.
The "packet framework" section under `* [port](@ref rte_port.h):` and similar subsections
have a term (header name) followed by a reference link.
This is a typical term/description pattern that RST definition lists handle better than nested bullets.

Example pattern:
```markdown
  * [port](@ref rte_port.h):
    [ethdev](@ref rte_port_ethdev.h),
    [ring](@ref rte_port_ring.h),
    [frag](@ref rte_port_frag.h),
```

Consider restructuring as:
```markdown
  * [port](@ref rte_port.h):

ethdev
   @ref rte_port_ethdev.h

ring
   @ref rte_port_ring.h

frag
   @ref rte_port_frag.h
```

However, the current format appears to be an established convention in this file
(used throughout for grouping related headers under a category).
If this format is intentional and consistent with the rest of the file, no change is needed.

## Summary

**Must fix (Error):**
- Patch 1/7: Variable name mismatch in `lib/meson.build` warning message (`doc_dir` vs `d`)

**Should consider (Warning):**
- Patch 1/7: Add validation that doc file parsing produces non-empty results
- Patch 7/7: Evaluate whether definition lists would improve structure (not a requirement if current format is intentional)
