Subject: [RFC net-next 0/2] add ethtool ops support for fresh device features

As Jakub Kicinski comment in patch:
https://lore.kernel.org/netdev/20220125195508.585b0c40@kicinski-fedora-PC1C0HJN.hsd1.ca.comcast.net/
, there are no ethtool command similar to ethtool -k for features contained
entirely to the driver. Fresh device features such as tx push need this
kind of command to set/get feature attributes.

So this patch adds new ethtool command support for new features belongs to 
the driver. The second patch adds hns3 support for this new command to 
configure tx push feature. This command can be easily reused by other 
features.

Comments are welcomed and i'm still testing this command.

  net: hns3: add ethtool set/get device features support for hns3 driver
