From a41f593f1bce27cd94eae0e85a8085c592b14b30 Mon Sep 17 00:00:00 2001 From: Ferruh Yigit Date: Fri, 11 Feb 2022 19:11:42 +0000 Subject: [PATCH] ethdev: introduce generic dummy packet burst function [ upstream commit a41f593f1bce27cd94eae0e85a8085c592b14b30 ] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Multiple PMDs have dummy/noop Rx/Tx packet burst functions. These dummy functions are very simple, introduce a common function in the ethdev and update drivers to use it instead of each driver having its own functions.
