## WARNINGS

None identified.

## INFO

**Improved diagnostic logging**  
The patch adds the Rx queue index to the debug log message and clarifies which mini CQE compression format is actually in use versus what was configured. The existing log only showed the configured format (`priv->config.cqe_comp_fmt`), but the patch now logs both the effective format in use for this queue (`rxq_data->mcqe_format`) and the configured format. This is a useful diagnostic improvement when debugging CQE compression behavior across multiple queues.

The format specifier change from `%d` to `%u` for `priv->config.cqe_comp_fmt` is correct since configuration values are typically unsigned.

**Minor wording suggestion**  
The log message could be slightly more grammatical with a verb:
```c
"Port %u Rx queue %u: CQE compression enabled, format %u (configured: %u)"
```
However, the existing wording is clear and consistent with DPDK's terse logging style, so this is optional.
