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

### Warnings

**drivers/meson.build and lib/meson.build: Variable used before verification**

The code reads `doc_indexed_headers` and `doc_built_dirs` before checking if they were successfully populated. If the `run_command()` calls fail silently or produce empty output, the `in` checks could behave unexpectedly.

Suggested fix:
```python
# In meson.build after each run_command(), verify the result is not empty:
if doc_indexed_headers.length() == 0
    error('Failed to parse doc_index_file or file is empty')
endif
if doc_built_dirs.length() == 0
    error('Failed to parse doc_build_file or file is empty')
endif
```

**lib/meson.build line 220: Use of undefined variable `doc_dir`**

The warning message references `doc_dir` which is not defined in scope. It should be `d`.

```python
# Line 220, change:
warning('public header directory @0@ is not listed in @1@'.format(doc_dir, doc_build_path))
# To:
warning('public header directory @0@ is not listed in @1@'.format(d, doc_build_path))
```

### Info

**Minor formatting inconsistency**

The BPF section uses a nested list with `*` bullets while other multi-item sections use inline links. For consistency, consider using the same format as other sections (e.g., "device specific", "packet framework port").

Example - current:
```markdown
  * BPF:
    [load and execute](@ref rte_bpf.h),
    [machine code](@ref bpf_def.h),
    ...
```

Could be:
```markdown
  [BPF](@ref rte_bpf.h),
  [BPF def](@ref bpf_def.h),
  ...
```

This is a minor style preference for documentation consistency, not a functional issue.

## Summary

The patch series overall is well-structured and addresses a real gap in DPDK documentation coverage. The main issues are:

1. **Warning (Patch 1)**: Undefined variable `doc_dir` in lib/meson.build line 220 -- must be fixed to `d`
2. **Warning (Patch 1)**: Missing validation that parsed documentation lists are non-empty
3. **Info (Patch 7)**: Minor formatting inconsistency in RST documentation (consider using definition lists or keeping consistent inline style)

The Doxygen typo fixes (patches 3-4) and the addition of missing headers to documentation (patches 5-7) are straightforward and correct.
