Version 1.0.1 brought the following changes:
[v1.0.1] - 2021-11-26
Primarily fixes a few issues in the kernel module that were found
during a quick review from Russell King:

- mdio: The mvls subcommand now supports flushing the ATU
- mdio-netlink: Plug some glaring holes around integer overflows of
the PC.
- mdio-netlink: Release reference to MDIO bus after a transaction
completes.
So, update to the latest version and switch the kernel module back
to fetching tarballs like the userspace tool does.

mdio is a low-level Linux debug tool for communicating with devices attached an MDIO bus. It improves on existing tools in this space in a few important ways:
MDIO buses are directly addressable. Previous solutions relied on at least one Ethernet PHY on the bus being attached to a net device, which is typically not the case when the device is an Ethernet switch for example.
Complex operations can be performed atomically. The old API only supported a single read or write of a single register. mdio sends byte code to the mdio-netlink kernel module that can perform multiple operations, store intermediate values, loop etc. As a result, things like read/mask/write operations and accesses to paged PHYs can be performed safely.
