Bleep bloop. Greetings Gregory Rose, I am a robot and I have tried out your patch. Thanks for your contribution. I encountered some error that I wasn't expecting. See the details below. Patch skipped due to previous failure. Please check this out. If you feel there has been an error, please email aconole@redhat.com Thanks, 0-day Robot

Since the openvswitch project inception it has had support for building a Linux kernel module to support the OVS kernel datapath. Since Linux kernel release 5.8 support for newer kernels has been deprecated. Now is the time to fully discontinue support for building the openvswitch kernel driver. Since Linux 5.9 the Linux built-in openvswitch kernel driver supports all necessary features and functions of the kernel datapath and the need to support this additional "out of tree" kernel module is gone. Remove the --with-linux configuration support from the acinclude.m4 configuration and warn user it is not supported any longer.
