Using sysfs's xprt_state attribute, mark a particular transport offline. It will not be picked during the round-robin selection. It's not allowed to take the main (1st created transport associated with the rpc_client) offline. Also bring a transport back online via sysfs by writing "online" and that would allow for this transport to be picked during the round- robin selection.
