[PATCH OLK-6.6] fix: fix version showed in ethtool
by s00851154 11 Oct '24

11 Oct '24

From: Shi Jing <shijing34(a)huawei.com> Fix the version in the output of ethtool commands from empty to the kernel version. Use the macro HINIC3_NIC_DRV_VERSION to record driver changes for developers. The last number 1.0.X grow as minor changes, like this revision which does not affect the main functions. The middle number 1.X.1 iterates with changes to drivers functionality and fixing of serious bugs, and the first one X.0.1 means the number of releases of the driver.
