Currently, master devices (bonding, bridge, team) manually call
netdev_compute_master_upper_features() scattered throughout their port
add/remove operations. This approach requires each driver to remember
to update features at the right times and leads to code duplication.

The series adds a new ndo_update_offloads callback that is automatically
invoked during feature updates when upper/lower device relationships change.
This centralizes the feature computation flow and removes the burden
from individual drivers.  

I'm sorry for the late feedback, but I think the driver cleanup and
simplification is not worthy the core complexity and the new NDO added.

+1 FWIW, I didn't want to be negative but I felt the same way..
We are always one step away from an inf loop propagating the features
it's a delicate space :S
