SDP is an IB-specific upper layer protocol. It defines a standard wire protocol to support stream sockets 
networking over IB. SDP enables sockets-based applications to take advantage of the enhanced 
performance features provided by IB and achieves lower latency and higher bandwidth than IPoIB 
running sockets-based applications. It provides a high-performance, zero-copy data transfer protocol for 
stream-socket networking over an IB fabric. You can configure the driver to automatically translate TCP 
to SDP based on source IP, destination, or application name. 

SDP uses the same IP addresses and interface names as IPoIB. Configure the IPoIB IP interfaces if you 
have not already done so. (See
