[PATCHv3 net-next 0/5] 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.

v3:
a) fix hw_enc_features asign order (Sabrina Dubroca)
b) set virtual dev feature defination in netdev_features.h (Jakub Kicinski)
c) remove unneeded err in team_del_slave (Stanislav Fomichev)
d) remove NETIF_F_HW_ESP test as it needs to be test with GSO pkts (Sabrina Dubroca)

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
