From 157d00901f97e3b77fe94938ef59cbe77d1c149a Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Mon, 25 Mar 2019 13:44:24 +0800 Subject: [PATCH] net/ice/base: add functions for ethertype filter Add API ice_remove_eth_mac and ice_add_eth_mac to support adding / removing ethertype (or MAC) based filter rules. PMD driver can use these APIs to enable related rte_flow rule.
