From 5aeb286fe51a54512630004516333787a0470695 Mon Sep 17 00:00:00 2001 From: Chenxu Di Date: Wed, 8 Jul 2020 01:18:37 +0000 Subject: [PATCH] net/i40e: add private APIs for flow filtering The legacy filter API will be superseded by rte_flow. There are also several small features which can not be implemented in rte_flow. This patch re-implemented these features as private API. Three APIs are added: rte_pmd_i40e_get_fdir_info. rte_pmd_i40e_get_fdir_stats. rte_pmd_i40e_set_gre_key_len.
