Matan Barak 045959db65 IB/cma: Add configfs for rdma_cm
Users would like to control the behaviour of rdma_cm.
For example, old applications which don't set the
required RoCE gid type could be executed on RoCE V2
network types. In order to support this configuration,
we implement a configfs for rdma_cm.

In order to use the configfs, one needs to mount it and
mkdir <IB device name> inside rdma_cm directory.

The patch adds support for a single configuration file,
default_roce_mode. The mode can either be "IB/RoCE v1" or
"RoCE v2".

---help---
Core support for InfiniBand (IB). Make sure to also select
any protocols you wish to use as well as drivers for your
InfiniBand hardware.

config INFINIBAND_USER_MAD
tristate "InfiniBand userspace MAD support"
depends on INFINIBAND
---help---
Userspace InfiniBand Management Datagram (MAD) support. This
is the kernel side of the userspace MAD support, which allows
userspace processes to send and receive MADs. You will also
need libibumad from <http://www.openfabrics.org/downloads/management/>.
config INFINIBAND_USER_ACCESS
tristate "InfiniBand userspace access (verbs and CM)"
select ANON_INODES
---help---
Userspace InfiniBand access support. This enables the
kernel side of userspace verbs and the userspace
communication manager (CM). This allows userspace processes
to set up connections and directly access InfiniBand
hardware for fast-path operations. You will also need
libibverbs, libibcm and a hardware driver library from
<http://www.openfabrics.org/git/>.

default y
config INFINIBAND_ON_DEMAND_PAGING
bool "InfiniBand on-demand paging support"
depends on INFINIBAND_USER_MEM
select MMU_NOTIFIER
default y
---help---
On demand paging support for the InfiniBand subsystem.
Together with driver support this allows registration of
memory regions without pinning their pages, fetching the
pages on demand instead.
config INFINIBAND_ADDR_TRANS
bool
depends on INFINIBAND
default y
config INFINIBAND_ADDR_TRANS_CONFIGFS
bool
depends on INFINIBAND_ADDR_TRANS && CONFIGFS_FS && !(INFINIBAND=y && CONFIGFS_FS=m)
default y
---help---
ConfigFS support for RDMA communication manager (CM).
This allows the user to config the default GID type that the CM
uses for each device, when initiaing new connections.
