ixgbe-5.22.25 not supported by netmap

[nolsen42]

Latest ixgbe version provided by intel is 5.22.25, which is not available on sourceforge since intel moved to their own github repo. Even if you manually download the file and set the version with --select-version=ixgbe:5.22.25, it will fail during make because its missing the patch file needed.

If you use latest ixgbe version available on netmap, which is 5.20.10, it will not compile on my machine. I am running 6.8.0-51-generic as my kernel.

So I am pretty much going nowhere with this, and cannot use netmap at all.
