[PATCHv2 net-next 0/5] net: common feature compute for upper interface

[Hangbin Liu <liuhangbin@gmail.com>]

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. (Ido Schimmel)

Hangbin Liu (5):
  net: add a common function to compute features from lowers devices
  bonding: use common function to compute the features
  team: use common function to compute the features
  net: bridge: use common function to compute the features
  selftests/net: add offload checking test for virtual interface
