From: Wei Zhao Date: Wed, 16 Oct 2019 18:33:56 +0000 (+0800) Subject: net/ice: rework switch filter X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=47d460d63233bcdc80748cecf0b74ec85fe1a43c;p=dpdk.git net/ice: rework switch filter The patch reworks packet process engine's binary classifier (switch) for the new framework. It also adds support for new packet type like PPPoE for switch filter.
