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. v2: a) remove hard_header_len setting. I will set needed_headroom for bond/team in a separate patch as bridge has it's own ways. (Ido Schimmel) b) Add test file to Makefile, set RET=0 to a proper location.
