> Subject: [PATCH] net/mlx5: fix modify field action order for IPv6
> Mellanox hardware can only modify any packet field in 32-bit chunks, which
> means 4 such chunks are needed to modify an IPv6 address.
> The modification order of these chunks starts from the most significant bits
> for the IPv6 address. That leads to confusing results when trying to modify
> either source or destination address via the MODIFY_FIELD action. Fix the
> order of 32-bit chunks for IPv6 addresses modification by starting from the
> least significant bits.
