[PATCH v2 0/5] add abstractions for network device drivers

[FUJITA Tomonori <tomo@exabit.dev>]

From: FUJITA Tomonori <fujita.tomonori@gmail.com>

This patchset adds minimum abstractions for network device drivers and
Rust dummy network device driver, a simpler version of drivers/net/dummy.c.

The dummy network device driver doesn't attach any bus such as PCI so
the dependency is minimum. Hopefully, it would make reviewing easier.

Changes since v1:
- avoids listing all the operations in net_device_ops and ethtool_ops
- renames the dummy device driver (rust_dummy to rust_net_dummy)
- removes atomic ops in the dummy device driver
- uses Opaque for rtnl_link_stats64 instead of raw pointer
- simplifies the code (cast, static, etc)

Thanks a lot for the comments on v1!

  rust: core abstractions for network device drivers
  rust: add support for ethernet operations
  rust: add support for get_stats64 in struct net_device_ops
  rust: add methods for configure net_device
  samples: rust: add dummy network driver
