x86: add support for AWS T3 instances
Amazon AWS T3 cloud instances require kernel support for the Elastic Fabric Adapter to access storage and for Elastic Network Adapter to use network interfaces. Since the Fabric Adapter is needed to access root filesystem, enable in x86_64 kernel. Elastic Network Adapter goes in a module, and add this module to default list in x86_64. The module is set to AutoLoad because AutoProbe does not seem to load it. Signed-off-by: Alberto Bursi <bobafetthotmail@gmail.com>
