Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull base rdma updates from Doug Ledford: "Round one of 4.8 code: while this is mostly normal, there is a new driver in here (the driver was hosted outside the kernel for several years and is actually a fairly mature and well coded driver). It amounts to 13,000 of the 16,000 lines of added code in here.
Summary:
- Updates/fixes for iw_cxgb4 driver - Updates/fixes for mlx5 driver - Add flow steering and RSS API - Add hardware stats to mlx4 and mlx5 drivers - Add firmware version API for RDMA driver use - Add the rxe driver (this is a software RoCE driver that makes any Ethernet device a RoCE device) - Fixes for i40iw driver - Support for send only multicast joins in the cma layer - Other minor fixes"

Soft RoCE driver
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.
