*******************************************************************************
WARNING: The Infiniband Verbs opcode Send With Invalidate is either not
supported or is not functional with the current version of libibverbs installed
on this system. Please upgrade to at least version 1.1.

Beginning with Linux kernel 4.14, the kernel NVMe-oF initiator leverages Send
With Invalidate RDMA operations to improve performance. Failing to use the
Send With Invalidate operation on the NVMe-oF target side results in full
functionality, but greatly reduced performance. The SPDK NVMe-oF target will
be unable to leverage that operation using the currently installed version
of libibverbs, so Linux kernel NVMe-oF initiators based on kernels greater
than or equal to 4.14 will see significantly reduced performance.
