Hangbin Liu says:

====================
net: common feature compute for upper interface

Some high-level virtual drivers need to compute features from their
lower devices, but each currently has its own implementation and may
miss some feature computations. This patch set introduces a common function
to compute features for such devices.

Currently, bonding, team, and bridge have been updated to use the new
helper.
