With DPDK 20.11 release, the igb_uio module is no more part of DPDK.
There are use cases where this module is required, for example while
testing the virtual ports in OvS, the virtual ports are bound to
igb_uio module inside a VM. So, this patch provides a Makefile
which can be used to build this module and use as needed.

Before building this module, the user is expected to build the
DPDK using meson build system and make sure that the required
libraries are installed in the path /usr/local

Hi Thomas/Ferruh,

It looks like this patch is not yet merged to
https://git.dpdk.org/dpdk-kmods/.

This impacts the 20.11-rc1 testing which needs the igb_uio driver. Is there
any reason to not merge this?

Regards,
Kalesh

Please don't hard-code values that are provided programmatically. Use
pkgconfing instead:

$(shell pkg-config --variable=includedir libdpdk)

> +RTE_KERNELDIR ?= /lib/modules/`uname -r`/build

This is not a dpdk specific location so it doesn't need an RTE prefix.
While there isn't a unique way of calling this, the most common name I
see being used is KSRC.
