Subject: [PATCH v3 4/5] net/mlx5: add NAT64 action support in rule creation
Date: Tue, 20 Feb 2024 16:37:30 +0200	[thread overview]
Message-ID: <20240220143731.295140-5-bingz@nvidia.com> (raw)
In-Reply-To: <20240220143731.295140-1-bingz@nvidia.com>

The action will handle the IPv4 and IPv6 headers translation. It will
add / remove IPv6 address prefix by default.

To use the user specific address, another rule to modify the
addresses of the IP header is needed.
