# DPDK Patch Review

## ERRORS

None.

## WARNINGS

None.

## INFO

**Definition of 1600G in lib/ethdev/rte_ethdev.h:**
The comment spans multiple lines explaining the IEEE standardization status.
While informative, this is unusual placement for a multi-line rationale comment
in the middle of a `#define` block.
DPDK typically reserves such explanatory comments for header documentation sections,
with in-line `#define` comments being brief annotations only.

Consider moving the standardization rationale to the section header comment
("Link speed" at line 296-ish) where context about speed progression is more naturally placed,
leaving only the brief `/**< 1.6 Tbps */` annotation on the define itself.

This is a minor style preference and does not affect correctness.
