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.
v4: * update needed_{headroom, tailroom} in the common helper (Ido Schimmel) * remove unneeded err in team (Stanislav Fomichev) * remove selftest as `ethtool -k` does not test the dev->*_features. We can add back the selftest when there is a good way to test. (Sabrina Dubroca)
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 (4): 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
