Build OFED drivers and userspace components against the kernel
source tree similar to Intel's NIC drivers.

OFED installers create Debian packages of their own tageting the
kernel version defined in the build invocation if DKMS is omitted.
Script builds with supporting components for VPP to permit handoff
of function to the underlying hardware as appropriate. Updating the
version is fairly trivial along with adding patching as needed to
handle kCFI and hardening measures as they are introduced.

Testing:
  Tested against GCC-built Linux Hardened kernel with the various
additions from PR 132 - sustained line-rate testing against 4x100g
links on a single machine at a hair below 200g for each LACP pair.

All VyOS kernel modules must live in the appropriate module directory,
example: /lib/modules/6.6.41-amd64-vyos/

In addition we do not abbreviate script options to make reading easier,
without call --help all the time.
