It is time to remove support for the ovs kernel driver and push towards use of the upstream linux openvswitch kernel driver in it's place [1].
1. https://mail.openvswitch.org/pipermail/ovs-dev/2022-april/393292.html Changes in V2: * Removed the Linux datapath and fixed up various Makefiles to adjust * Moved openvswitch.h from datapath/linux/compat/include to include/linux and fixed up the Makefiles to adjust * Removed further instances in utilities and auxiliary files where the --with-linux configuration command was still being used. * Changed order of patches to (hopefully) fix up some robot auto-test errors Changes in V3: * Squashed the two patches removing rhel specs due to interdependence between the two that caused build errors between application of each of the patches * Moved the changes to acinclude.m4 towards the end of the series Changes in V4: * Changed up the order of the patches again to fix robot errors * Added back most of the tests in .github/workflows/build-and-test.yml * Removed xenserver and related documentation, test scripts and makefile dependencies Changes in V5: * Squashed two patches from previous series into a single patch. There was no good reason to separate changes to auxiliary and utilities from the removal of the Linux datapath and the two patches had a tricky dependency between them. Best to combine them. * Various cleanups, title changes and amended commit messages as suggested by David Marchand in his reviews. * Drops the xenserver removal patch - this patch causes 'make check' failures and there is no reason why it can't be submitted separately. * With these changes the github workflows build and test work without errors: https://github.com/gvrose8192/ovs-experimental/runs/7330169845?check_suite_focus=true Still to do: * Submit the patch to remove xenserver separately once I figure out why the removal causes 'make check' errors for a few interface reconfiguration tests.
