libibverbs is a library that allows userspace processes to use RDMA
 "verbs" as described in the InfiniBand Architecture Specification and
 the RDMA Protocol Verbs Specification. iWARP ethernet NICs support
 RDMA over hardware-offloaded TCP/IP, while InfiniBand is a
 high-throughput, low-latency networking technology. InfiniBand host
 channel adapters (HCAs) and iWARP NICs commonly support direct
 hardware access from userspace (kernel bypass), and libibverbs
 supports this when available.
 .
 An RDMA driver consists of a kernel portion and a user space portion.
 This package contains the user space verbs drivers:
