From 8973508a0cb3af9178c532c8073784800804e918 Mon Sep 17 00:00:00 2001 From: Remy Horton Date: Fri, 11 May 2018 13:28:44 +0100 Subject: [PATCH] net/i40e: fix missing port representor data-path This patch adds Rx and Tx burst functions to the i40e Port Representors, so that the implementation within this PMD can be tested using applications such as testpmd which require data-path functionality.
