+# Configure Soft-RoCE (RXE):
+
+Load rdma_rxe kernel module using the rxe_cfg script included in the librxe RPM:
+
+rxe_cfg start (this might require sudo or root privileges)
+
+Create RXE device over network interface (e.g. eth0):
+
+rxe_cfg add eth0
+
+Use the status command to display the current configuration:
+rxe_cfg status
+
+If configured successfully, you should see output similar to the following:
+ Name Link Driver Speed NMTU IPv4_addr RDEV RMTU
+ eth0 yes mlx4_en rxe0 1024 (3)
+
+If you are using a Mellanox HCA: Need to make sure that the mlx4_ib kernel module is not loaded (modprobe –rv mlx4_ib) in the soft-RoCE machine.
+Now you have an Infiniband device called “rxe0” that can be used to run any RoCE app.

-# librxe-dev
-Development repository for RXE user space code.
-Soft RDMA over Ethernet (RoCE) Driver
-
-Source
-
-Kernel Space Driver
-
-This repository contains a full kernel source tree, with the RoCE driver code located in the directory drivers/infiniband/hw/rxe.
-
-Github: https://github.com/SoftRoCE/rxe-dev.git
-Active Branch: master-next
-User Space Library
-
-Github: https://github.com/SoftRoCE/librxe-dev.git (this repository)
-Current Version: librxe-1.0.0
-Build Instructions
-
-Compile and install kernel:
-
-Clone kernel git:
-git clone https://github.com/SoftRoCE/rxe-dev.git
-Compile kernel:
-Enter the source directory cd rxe-dev
-cp /boot/config-$(uname –r) .config
-make menuconfig
-Need to enable “Software RDMA over Ethernet (RoCE) driver” in category "Device Drivers -> Infiniband"
-Need to enable CONFIG_INFINIBAND_ADDR_TRANS=y and CONFIG_INFINIBAND_ADDR_TRANS_CONFIGFS=y in new config file .config
-make –j 32
-make modules_install
-make install
-Verify that the new kernel entry is added (e.g. to grub); if not, need to add it manually.
-Boot with new kernel.
-Install user space library (librxe):
-
-Install the following package (example shown using RedHat):
-yum install perl-Switch (name might vary according to distribution)
-Make sure that the following upstream user space libraries are installed:
-libibverbs
-libibverbs-devel
-libibverbs-utils
-librdmacm
-librdmacm-devel
-librdmacm-utils
-Compile and install user space library librxe:
-git clone https://github.com/SoftRoCE/librxe-dev.git
-cd librxe-dev
-./configure --libdir=/usr/lib64/ --prefix=
-make
-make install
-Configure Soft-RoCE (RXE):

Very little of the rxe RADME.md is relevant with the kernel driver upstream, and the userspace provider part of this repository. Move the remaining bits to Documentation/rxe.md and delete the rest.
