Subject: [PATCH net-next 0/8] 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.
Sabrina Dubroca (8):
netdevsim: add more hw_features
selftests: netdevsim: add a test checking ethtool features
macsec: add some of the lower device's features when offloading
macsec: clean up local variables in macsec_notify
macsec: inherit lower device's TSO limits when offloading
selftests: move macsec offload tests from net/rtnetlink to
drivers/net/netdvesim
selftests: netdevsim: add test toggling macsec offload
selftests: netdevsim: add ethtool features to macsec offload tests
