====================
macsec: inherit lower device's features and TSO limits when offloading

When macsec is offloaded to a NIC, we can take advantage of some of
its features, mainly TSO and checksumming. This increases performance
significantly. Some features cannot be inherited, because they require
additional ops that aren't provided by the macsec netdevice.

We also need to inherit TSO limits from the lower device, like
VLAN/macvlan devices do.

This series also moves the existing macsec offload selftest to the
netdevsim selftests before adding tests for the new features. To allow
this new selftest to work, netdevsim's hw_features are expanded.
