Pull rdma updates from Jason Gunthorpe:
 "This has been a smaller cycle with many of the commits being smallish
  code fixes and improvements across the drivers.

   - Driver updates for bnxt_re, cxgb4, hfi1, hns, mlx5, nes, qedr, and
     rxe

   - Memory window support in hns

   - mlx5 user API 'flow mutate/steering' allows accessing the full
     packet mangling and matching machinery from user space

   - Support inter-working with verbs API calls in the 'devx' mlx5 user
     API, and provide options to use devx with less privilege

   - Modernize the use of syfs and the device interface to use attribute
     groups and cdev properly for uverbs, and clean up some of the core
     code's device list management

   - More progress on net namespaces for RDMA devices

   - Consolidate driver BAR mmapping support into core code helpers and
     rework how RDMA holds poitners to mm_struct for get_user_pages
     cases

   - First pass to use 'dev_name' instead of ib_device->name

   - Device renaming for RDMA devices"

stacked (e.g: VLAN interfaces) but still have the same MAC
address as their parent device.
What: /sys/class/net/<iface>/dev_port
Date: February 2014
KernelVersion: 3.15
Contact: netdev@vger.kernel.org
Description:
Indicates the port number of this network device, formatted
as a decimal value. Some NICs have multiple independent ports
on the same PCI bus, device and function. This attribute allows
userspace to distinguish the respective interfaces.
Note: some device drivers started to use 'dev_id' for this
purpose since long before 3.15 and have not adopted the new
attribute ever since. To query the port number, some tools look
exclusively at 'dev_port', while others only consult 'dev_id'.
If a network device has multiple client adapter ports as
described in the previous paragraph and does not set this
attribute to its port number, it's a kernel bug.
