+Testing rdma-core userspace tools
+=================================
+
+Testing rdma-core using Linux software RoCE implementation:
+https://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet
+
+Using two systems with working TCP/IP configuration, for example:
+- Server IP: 192.168.123.10
+- Client IP: 192.168.123.20
+
+Make sure firewall configurations are appropriate. Routable RoCE v2
+uses udp/4791. ibv_rc_pingpong uses tcp/18515 for initial
+synchronization.
+
+Note: this test can be executed in two qemu virtual machines with
+bridged networking.
+
+
+Kernel configuration
+--------------------
+
+The Linux Kernel needs some InfiniBand configuration. In this example
+the kernel "rdma_rxe" driver is needed (CONFIG_RDMA_RXE=y). The Kernel
+config fragment file used for package test can be used as a starting
+point. See:
+
+ support/testing/tests/package/test_rdma_core/linux-rdma.fragment
+
+
+Buildroot package configuration
+-------------------------------
+
+For setting up a software RoCE link, the "rdma" program is needed. It
+is provided by the "iproute2" package, when "libmnl" is also
+selected. Make sure to have in your Buildroot configuration:
+
+ BR2_PACKAGE_IPROUTE2=y
+ BR2_PACKAGE_LIBMNL=y
+ BR2_PACKAGE_RDMA_CORE=y
+
+
+Setting up the rdma link
+------------------------
+
+On both server and client:
+
+ modprobe rdma_rxe
+ rdma link add rxe0 type rxe netdev eth0
+
+
+Testing with rping
+------------------
+
+On the server side, run the command:
+
+ rping -s -v
+
+On the client side, run the command:
+
+ rping -c -v -a 192.168.123.10
+
+
+Testing with ibv_rc_pingpong
+----------------------------
+
+To test with the pingpong example using the reliable connected (RC)
+transport:
+
+On the server side, run the command:
+
+ ibv_rc_pingpong -d rxe0 -g 1
+
+On the client side, run the command:
+
+ ibv_rc_pingpong -d rxe0 -g 1 192.168.123.10
