We should cover the uAPI and the tricky part of the handling please.
So off the top of my head main bits:
- the expected attributes on lessor and lessee via Netlink
- destroying the netkit with MP attached
- checking the state via YNL,
- attaching MP from the main dev to make sure we didn't leave
anything behind
- destroying phys dev while netkit exists (prolly netdevsim :S)
- making sure XDP can't be attached on phys dev when MP is installed
via netkit
... whatever else you found to be tricky in the implementation.
