This old script relied on deprecated stuff, and especially make.
It also applied some scary 666 permissions on files under /dev/vfio.

Its deprecation had been notified in a previous release, remove it.

-Quick Start Setup Script
-========================
-
-The dpdk-setup.sh script, found in the usertools subdirectory, allows the user to perform the following tasks:
-
-*   Build the DPDK libraries
-
-*   Insert and remove the DPDK IGB_UIO kernel module
-
-*   Insert and remove VFIO kernel modules
-
-*   Insert and remove the DPDK KNI kernel module
-
-*   Create and delete hugepages for NUMA and non-NUMA cases
-
-*   View network port status and reserve ports for DPDK application use
-
-*   Set up permissions for using VFIO as a non-privileged user
-
-*   Run the test and testpmd applications
-
-*   Look at hugepages in the meminfo
-
-*   List hugepages in ``/mnt/huge``
-
-*   Remove built DPDK libraries
-
-Once these steps have been completed for one of the EAL targets,
-the user may compile their own application that links in the EAL libraries to create the DPDK image.
-
-Script Organization
--------------------
-
-The dpdk-setup.sh script is logically organized into a series of steps that a user performs in sequence.
-Each step provides a number of options that guide the user to completing the desired task.
-The following is a brief synopsis of each step.
-
-**Step 1: Build DPDK Libraries**
-
-Initially, the user must select a DPDK target to choose the correct target type and compiler options to use when building the libraries.
-
-The user must have all libraries, modules, updates and compilers installed in the system prior to this,
-as described in the earlier chapters in this Getting Started Guide.
-
-**Step 2: Setup Environment**
-
-The user configures the Linux* environment to support the running of DPDK applications.
-Hugepages can be set up for NUMA or non-NUMA systems. Any existing hugepages will be removed.
-The DPDK kernel module that is needed can also be inserted in this step,
-and network ports may be bound to this module for DPDK application use.
-
-**Step 3: Run an Application**
-
-The user may run the test application once the other steps have been performed.
-The test application allows the user to run a series of functional tests for the DPDK.
-The testpmd application, which supports the receiving and sending of packets, can also be run.
-
-**Step 4: Examining the System**
-
-This step provides some tools for examining the status of hugepage mappings.
-
-**Step 5: System Cleanup**
-
-The final step has options for restoring the system to its original state.
-
-Use Cases
----------
-
-The following are some example of how to use the dpdk-setup.sh script.
-The script should be run using the source command.
-Some options in the script prompt the user for further data before proceeding.

-
-    The dpdk-setup.sh script should be run with root privileges.
