Add a driver framework for EEA that will be available in the future.
This driver is currently quite minimal, implementing only fundamental
core functionalities. Key features include: I/O queue management via
adminq, basic PCI-layer operations, and essential RX/TX data
communication capabilities. It also supports the creation,
initialization, and management of network devices (netdev). Furthermore,
the ring structures for both I/O queues and adminq have been abstracted
into a simple, unified, and reusable library implementation,
facilitating future extension and maintenance.
