Subject: [PATCH v2 2/2] net/mlx5: support new RSS symmetric hash function
Date: Sun, 27 Aug 2023 16:17:45 +0800	[thread overview]
Message-ID: <20230827081745.31906-2-xuemingl@nvidia.com> (raw)
In-Reply-To: <20230807115456.17478-1-xuemingl@nvidia.com>

This patch supports the new RSS symmetric hash function:
RTE_ETH_HASH_FUNCTION_SYMMETRIC_TOEPLITZ_SORT

The new hash function makes symmetric hash result by swapping
the source and destination IP and L4 port automatically.
