// The basic idea behind this test structure is that one end will run
// in "slave" mode and the other in "master" mode. Typically, the slave
// will run on a target platform with the master running on a host.
//
// The slave starts up by listening for a connection on the "SLAVE_PORT".
// In order for the testing to require the minimum stack support, this
// connection (and the protocol) will use UDP.
//
// The master will connect to the slave and send it a request over this
// connection. Once the slave accepts the request, then master and slave
// will execute the operation, typically a test. The control connection
// will remain active until the master sends a 'disconnect' request. The
// control connection will be broken after the reply to this request has
// been sent.
