This is (was?) required for static IP addresses, as some switches might take quite some time to update their internal routing tables, during which time any connect() attempt will return -EHOSTUNREACH. And as the kernel code does has no concept of an initial connection establishment it will fail the connection. So we're doing a discovery first to setup the connection, thus ensuring that the kernel will be able to log into the server properly.
