From 858b4575513fe72dce95370944b0da237b755204 Mon Sep 17 00:00:00 2001
From: Dave Wallace <dwallacelf@gmail.com>
Date: Thu, 15 Oct 2020 15:22:22 -0400
Subject: [PATCH] backport dpdk usertools support python 3 only
Applicable usertools section of DPDK patch:
http://git.dpdk.org/dpdk/commit/?id=3f6f83626cf4967a99382a6518a614a1bf3d2c20
Required to avoid build failure of 'make install-ext-deps' on CentOS-8 due
to brp-mangle-shebangs failing on un-versioned python shebang (e.g.
'#! /usr/bin/env python'.
