** Description changed:

  [Impact]
  Newer revisions of hns3 support toggling the  rx-vlan-filter feature, but the 
driver does not allow it.
  
  [Test Case]
  Currently the command:
-   $ sudo strace ethtool -K <hns3-dev> rx-vlan-filter off
+   $ sudo ethtool -K <hns3-dev> rx-vlan-filter off
  reports:
-   Could not change any device features
+   Could not change any device features
  Even on hardware that supports this feature.
  
  [Fix]
  Apply this upstream commit:
  3e85af6a6812d net: hns3: Add vlan filter setting by ethtool command -K
  
  [Regression Risk]
  I've regression tested on hns3 hardware that does not support this feature, 
and it worked as it should.
