Public bug reported:

The ubuntu_dgx_mofed_build.dkms test currently assumes that only MOFED
dkms modules are installed but nothing else.

>From autotest-client-tests/ubuntu_dgx_mofed_build/check-mofed-
modules.sh:

# This test assumes that the only modules installed here are the MOFED ones.
# If other DKMS packages are installed that will throw it off.
echo "INFO: Scanning for available MOFED kernel modules..."
ls /lib/modules/$(uname -r)/updates/dkms | sort > ${actual}

if diff -u ${expected} ${actual}; then
    echo "INFO: Success: Actual module list matches expected module list."
    exit 0
fi

echo "ERROR: Actual modules list does not match expected modules list" 1>&2
exit 1

This assumption is currently not met when testing bionic:linux on
nvidia-dgx-2:
