---help---
SMC-R provides a "sockets over RDMA" solution making use of
RDMA over Converged Ethernet (RoCE) technology to upgrade
AF_INET TCP connections transparently.
The Linux implementation of the SMC-R solution is designed as
a separate socket family SMC.
Warning: SMC will expose all memory for remote reads and writes
once a connection is established. Don't enable this option except
