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.

On buildbots the build fails because git isn't finding any git repo and
then AC_INIT refuses to run:

fatal: not a git repository (or any parent up to mount point /)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
configure.ac:5: error: AC_INIT should be called with package and version arguments

Address this by substituting the git command with $(PKG_VERSION).

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.
