# DPDK Patch Review

Reviewing patch: "examples/l3fwd: sync cli options with documentation"

## ERRORS

None identified.

## WARNINGS

None identified.

## INFO

**Documentation synchronization:**
This patch brings print_usage() and l3_forward.rst into alignment by adding previously undocumented options to both the help text and the user guide.  The verification script in the commit message confirms all 25 active options now appear in both locations, which is good practice for user-facing documentation.

**Removed obsolete option:**
The patch correctly removes `--hash-entry-num` from the documentation, matching the code where this option has been non-functional since commit f5251734c5e1.  The removal is documentation-only and does not affect any code paths.

**Descriptions added:**
The `--disable-rss` and `--relax-rx-offload` options now have descriptions in print_usage(), making the help text more useful.  The `--relax-rx-offload` description explains the behavior (masking unsupported offloads and enabling software validation) which helps users understand when to use it.

Review-Result: CLEAN
