• Ensure offloaded rules preserve expected security semantics—unexpected fallbacks can create gaps.
• Authentication and integrity of control-plane interactions with NIC firmware must be trusted; keep firmware/drivers up to date.
• Access control for who can program offloads (typically root) is critical.
