+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'.
