The Linux implementation of the SMC-R solution is designed as a separate socket family SMC. Select this option if you want to run SMC socket applications config SMC_DIAG tristate "SMC: socket monitoring interface" depends on SMC help Support for SMC socket monitoring interface used by tools such as smcss. if unsure, say Y. config SMC_LO bool "SMC intra-OS shortcut with loopback-ism" depends on SMC default n help SMC_LO enables the creation of an Emulated-ISM device named loopback-ism in SMC and makes use of it for transferring data when communication occurs within the same OS. This helps in convenient testing of SMC-D since loopback-ism is independent of architecture or hardware. if unsure, say N.
