Collection of tests for RDMA micro-benchmark

This is a collection of tests written over uverbs intended for use as a performance micro-benchmark. The tests may be used for HW or SW tuning as well as for functional testing. The collection contains a set of bandwidth and latency benchmark such as: * Send - ib_send_bw and ib_send_lat * RDMA Read - ib_read_bw and ib_read_lat * RDMA Write - ib_write_bw and ib_wriet_lat * RDMA Atomic - ib_atomic_bw and ib_atomic_lat * Native Ethernet (when working with MOFED2) - raw_ethernet_bw, raw_ethernet_lat
