From: Michael Ellerman The iseries_veth driver has a logic bug which means it will erroneously send packets to LPARs for which we don't have a connection. This usually isn't a big problem because the Hypervisor call fails gracefully and we return, but if packets are TX'ed during the negotiation of the connection bad things might happen. Regardless, the right thing is to bail early if we know there's no connection.
