librdmacm/rstream: Reduce default transfer count
PATCH 1/2 librdmacm/rstream: Reduce default transfer count
From: Sean Hefty <[email protected]>
1 million ping-pong transfers takes over 3 seconds to complete, and I'm impatient. Reduce the default number of transfers for small messsages to speed up running performance tests, especially when running over slower connections, like TCP sockets or over a WAN.

PATCH 2/2 librdmacm/rsocket: Fix resetting O_NONBLOCK after calling shutdown
From: Sean Hefty <[email protected]>
Shutdown switches an rsocket from nonblocking to blocking to ensure that all data has been sent. After completing all transfers, it should switch back to nonblocking; this handles partial shutdown situations, where only half the connection is shut down. However, the code uses the value of '1' to set the nonblocking flag, rather than O_NONBLOCK. Fix this.
