With the new version (not submitted since it fails me) you can have a
look at my personal WIP branch:
=> https://github.com/cpaelzer/dpdk-stable-queue/commit/43b908fe83e9cd68b08e259c0ace26ec692bb737

Now "my SLE15" fails

[  232s] /home/abuild/rpmbuild/BUILD/dpdk-1623314498.43b908fe8/x86_64-default-linux-gcc/build/kernel/linux/kni/kni_net.c:791:20:
error: initialization from incompatible pointer type
[-Werror=incompatible-pointer-types]
[  232s]   .ndo_tx_timeout = kni_net_tx_timeout,
[  232s]                     ^~~~~~~~~~~~~~~~~~

The full log is at
https://build.opensuse.org/package/live_build_log/home:cpaelzer:branches:home:bluca:dpdk/dpdk-19.11/SLE_15/x86_64

That means now the check is now no more catching this SLE15 with their
linux-5.3.18-57.

I need to find what SLE_VERSION_CODE really is in that environment :-/
Sadly I don't have that system locally.

So the V3 will be delayed, but any additional input is welcome.

P.S. or I can't make an >= check on SLE_VERSION_CODE ...?
