Subject: [PATCH net-next] net/core: Replace driver version to be kernel version
Date: Thu, 23 Jan 2020 15:05:41 +0200	[thread overview]
Message-ID: <20200123130541.30473-1-leon@kernel.org> (raw)

From: Leon Romanovsky <leonro@mellanox.com>

In order to stop useless driver version bumps and unify output
presented by ethtool -i, let's overwrite the version string.

Before this change:
[leonro@erver ~]$ ethtool -i eth0
driver: virtio_net
version: 1.0.0
After this change:
[leonro@server ~]$ ethtool -i eth0
driver: virtio_net
version: 5.5.0-rc6+

Signed-off-by: Leon Romanovsky <leonro@mellanox.com>

I wanted to change to VERMAGIC_STRING, but the output doesn't
look pleasant to my taste and on my system is truncated to be
"version: 5.5.0-rc6+ SMP mod_unload modve".

After this patch, we can drop all those version assignments
from the drivers.

Inspired by nfp and hns code.
