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.
