Subject: [PATCH net-next v1] net/core: Replace driver version to be kernel version

From: Leon Romanovsky <leonro@...lanox.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@...er ~]$ ethtool -i eth0
driver: virtio_net
version: 1.0.0
After this change:
[leonro@...ver ~]$ ethtool -i eth0
driver: virtio_net
version: 5.5.0-rc6+

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