# DPDK Patch Review

## Patch Summary
This patch removes the "EXPERIMENTAL" designation from the Intel IDXD DMA driver in the MAINTAINERS file, indicating the driver is now considered stable.

## Review

### Errors
None identified.

### Warnings
**Missing release notes update:**
The patch changes the stability status of a driver from experimental to stable, which is a significant milestone that users and packagers need to know about. This should be documented in the current release notes under an appropriate section (e.g., "API Changes" or "Removed Items").

**Suggested fix:**
Add an entry to `doc/guides/rel_notes/release_<current>.rst`:

```rst
* **Removed experimental tag from Intel IDXD DMA driver.**

  The Intel IDXD DMA driver is no longer marked as experimental
  and is now considered stable API.
```

### Info
The change itself is straightforward and correct - it modifies only the MAINTAINERS file to remove the experimental designation. The commit message clearly states the rationale (driver has been stable for a long time).
