Currently, IntelCnaHardwareManager inherits GenericHardwareManager
which makes it a new "GenericHardwareManager" with "MAINLINE" priority.
This causes all other hardware-managers with lower priority than
"MAINLINE" never be used. To fix this, make IntelCnaHardwareManager
inherit basic HardwareManager.
