summary: Ensure that the broadcom-asic-control interface works.
details: |
The broadcom-asic-control interface allow access to broadcom asic kernel module.
# We need to run the broadcom-asic-control test very early. The reason is
# that this test will modprobe linux-*-bde which will try to allocate a
# huge page. One the system ran for a while no chunk of memory like this
# will be not be available and the kernel will oops with:
# "modprobe: page allocation failure: order:7, mode:0xxxx"
priority: 200
