Public bug reported:

[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
reports:
  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.
