# DPDK Patch Review

## Summary
This patch fixes Python formatting issues in the DTS (DPDK Test Suite) cryptodev_latency test suite by adding spaces around the `*` operator in f-string expressions, complying with PEP 8 style guidelines enforced by the `black` formatter.

## Review Findings

###  No Issues Found

This patch makes minimal, formatting-only changes to Python test code and does not introduce any correctness, style, or API compliance issues.

**Verified:**
- Changes are purely cosmetic (adding spaces: `'='*border_len` - `'=' * border_len`)
- No correctness bugs (no resource management, error handling, or logic changes)
- Python formatting follows DPDK guidelines (must comply with `black` formatter)
- Changes are in test code (`dts/tests/`), which does not require release notes per guidelines
- No deprecated API usage
- No forbidden tokens
- No C code style issues (this is Python)
- No API or ABI changes
- No documentation updates needed (formatting fix only)

**Conclusion:** This patch is ready for merge. It correctly addresses a Python formatting issue identified by updated tooling without introducing any problems.
