From: Steve Yang Date: Mon, 21 Jun 2021 08:03:42 +0000 (+0000) Subject: net/i40e: fix available RSS hash function X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c725221d09113bde89faa1e3c468e805fb335939;p=dpdk.git net/i40e: fix available RSS hash function i40e can support following rss hash function types: default/toeplitz, symmetric toeplitz, and simple_xor. However, when filter engine parses pattern action, it only supports symmetric toeplitz & default. Add simple_xor and toeplitz hash functions support when parsing pattern action.
