net: add a common function to compute features for upper devices
[ Upstream commit 28098defc79fe7d29e6bfe4eb6312991f6bdc3d3 ]
Some high level software drivers need to compute features from lower
devices. But each has their own implementations and may lost some
feature compute. Let's use one common function to compute features
for kinds of these devices.
The new helper uses the current bond implementation as the reference
one, as the latter already handles all the relevant aspects: netdev
features, TSO limits and dst retention.
