2016-08-04	Soft RoCE driver	Moni Shoua	1	-0/+1
	Soft RoCE (RXE) - The software RoCE driver ib_rxe implements the RDMA transport and registers to the RDMA core device as a kernel verbs provider. It also implements the packet IO layer. On the other hand ib_rxe registers to the Linux netdev stack as a udp encapsulating protocol, in that case RDMA, for sending and receiving packets over any Ethernet device. This yields a RDMA transport over the UDP/Ethernet network layer forming a RoCEv2 compatible device. The configuration procedure of the Soft RoCE drivers requires binding to any existing Ethernet network device. This is done with /sys interface. A userspace Soft RoCE library (librxe) provides user applications the ability to run with Soft RoCE devices. The use of rxe verbs ins user space requires the inclusion of librxe as a device specifics plug-in to libibverbs. librxe is packaged separately.

2016-03-10	IB/rdmavt: Create module framework and handle driver registration	Dennis Dalessandro	1	-0/+1
	This patch introduces the basics for a new module called rdma_vt. This new driver is a software implementation of the InfiniBand verbs and aims to replace the multiple implementations that exist and duplicate each others' code. While the call to actually register the device with the IB core happens in rdma_vt, most of the work is still done in the drivers themselves. This will be changing in a follow on patch this is just laying the groundwork for this infrastructure.
