Merge branch 'net-common-feature-compute-for-upper-interface'
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.
