Subject: [PATCH v1 0/3] Rust abstractions for network PHY drivers

This patchset adds Rust abstractions for network PHY drivers. It
doesn't fully cover the C APIs for PHY drivers yet but I think that
it's already useful. I implement two PHY drivers (Asix AX88772A PHYs
and Realtek Generic FE-GE). Seems they work well with real hardware.

The first patch introduces Rust bindings for the C APIs for network
PHY drivers.

The second patch adds the bindings to the ETHERNET PHY LIBRARY, and
also me as a maintainer of the Rust bindings (as Andrew Lunn
suggested).

The last patch introduces the Rust version of Asix PHY drivers,
drivers/net/phy/ax88796b.c. The features are equivalent to the C
version. You can choose C (by default) or Rust version on kernel
configuration.

You can find discussions on the RFC patches at rust-for-linux ml:
