[prefix=DPDK_KMODS,v6,2/2] linux/igb_uio: add Makefile to build the igb_uio module
Checks
Commit Message
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.
Since there is no more dependency on DPDK headers, this module can be
built simply by running make in the source dir

Please don't justify the use of igb_uio here.
(and I think it's wrong, you can always use VFIO except on very old kernels)

No need to talk about the old dependency here.
