It is time to remove support for the OVS kernel driver and push

in it's place [1].
This patch series represents a first attempt but there are a few
primary remaining issues that I have yet to address.
A) Removal of debian packing support for the dkms kernel driver
module. The debian/rules are not well known to me - I've never
actually made any changes in that area and do not have a
well formed understanding of how debian packaging works. I wil
attempt to fix that up in upcoming patch series.
B) Figuring out how the github workflow - I removed the tests I
could find that depend on the Linux kernel (i.e. they use
install_kernel() function. Several other tests are failing
that would not seem to depend on the Linux kernel. I need to
read and understand that code better.
C) There are many Linux specific source modules in the datapath that
will need eventual removal but some headers are still required for
the userspace code (which seems counterintuitive but...)
Reviews, suggestions, etc. are appreciated!

I would like to suggest at this time that rather than removing the OVS
Linux kernel path that we "freeze" it at Linux 5.8. This will make it
easier for some consumers of OVS that are continuing to support the
Linux kernel datapath in old distributions.
The ultimate goal of shifting toward DPDK and AFXDP datapaths is still
preserved but we are placing less burden on some consumers of OVS for
older Linux distributions.
Perhaps in suggesting removal of the kernel datapath I was being a bit
overly aggressive.
Thoughts? Concerns? Other suggestions?
Thanks,
- Greg
