[PATCH net-next v2 0/3] net: phy: add Rust reference driver for ET1011C

[Artem Lytkin]

This series adds a Rust reference driver for the LSI ET1011C PHY,
following the pattern established by the existing Rust Asix PHY driver
(ax88796b_rust.rs).

Patch 1 adds a speed() getter to phy::Device, needed to detect speed
changes in read_status.

Patch 2 exposes genphy_config_aneg() in the Rust PHY abstraction,
needed by PHY drivers that perform custom BMCR configuration before
calling the generic auto-negotiation setup.

Patch 3 adds the Rust ET1011C driver itself, implementing config_aneg
and read_status callbacks. It is a feature-equivalent port of the C
driver at drivers/net/phy/et1011c.c.

Changes since v1:
  - Added speed() getter to properly detect speed changes (Andrew Lunn)
  - read_status now only reconfigures registers when speed changes,
    matching the C driver behavior (Andrew Lunn)
  - Removed unrelated dim2 staging patches from the series
