Subject: [PATCH net-next v6 0/5] eea: Add basic driver framework for Alibaba Elastic Ethernet Adaptor

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.

Xuan Zhuo (5):
  eea: introduce PCI framework
  eea: introduce ring and descriptor structures
  eea: probe the netdevice and create adminq
  eea: create/destroy rx,tx queues for netdevice open and stop
  eea: introduce ethtool support
