From d654167641bf35601ff3ce0d545d3a6a32efc284 Mon Sep 17 00:00:00 2001 From: Xueming Li Date: Thu, 11 Mar 2021 13:13:24 +0000 Subject: [PATCH] ethdev: introduce representor type To support more representor type, this patch introduces representor type enum. The enum is subject to be extended to support new representor in patches upcoming. For each devarg structure, only one type supported.
