In order to stop useless driver version bumps and unify output presented by ethtool -i, let's set default version string. As Linus said in [1]: "Things are supposed to be backwards and forwards compatible, because we don't accept breakage in user space anyway. So versioning is pointless, and only causes problems." They cause problems when users start to see version changes and expect specific set of features which will be different for stable@, vanilla and distribution kernels. Distribution kernels are based on some kernel version with extra patches on top, for example, in RedHat world this "extra" is a lot and for them your driver version say nothing. Users who run vanilla kernels won't use driver version information too, because running such kernels requires knowledge and understanding. Another set of problems are related to difference in versioning scheme and such doesn't allow to write meaningful automation which will work sanely on all ethtool capable devices. Before this change: [leonro@erver ~]$ ethtool -i eth0 driver: virtio_net version: 1.0.0 After this change and once ->version assignment will be deleted from virtio_net: [leonro@server ~]$ ethtool -i eth0 driver: virtio_net version: 5.5.0-rc6+ Link: https://lore.kernel.org/ksummit-discuss/CA+55aFx9A=5cc0QZ7CySC4F2K7eYaEfzkdYEc9JaNgCcV25=rg@mail.gmail.com/ Link: https://lore.kernel.org/linux-rdma/20200122152627.14903-1-michal.kalderon@marvell.com/T/#md460ff8f976c532a89d6860411c3c50bb811038b Link: https://lore.kernel.org/linux-rdma/20200127060835.GA570@unicorn.suse.cz Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Acked-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
