Enabling network namespaces for RDMA CM will allow processes on different
namespaces to listen on the same port. In order to leave namespace support
out of the CM layer, this requires that multiple RDMA CM IDs will be able
to share a single CM ID.
This patch adds infrastructure to retrieve an existing listening ib_cm_id,
based on its device and service ID, or create a new one if one does not
already exist. It also adds a reference count for such instances
(cm_id_private.listen_sharecount), and prevents cm_destroy_id from
destroying a CM if it is still shared. See the relevant discussion [1].

Expose the service ID on an incoming CM or SIDR request to the event

In the case of IPoIB, and maybe in other cases, the network device is
managed by an upper-layer protocol (ULP). In order to expose this
network device to other users of the IB device, let ULPs implement
a callback that returns network device according to connection parameters.
The IB device and port, together with the P_Key and the GID should
be enough to uniquely identify the ULP net device. However, in current
kernels there can be multiple IPoIB interfaces created with the same GID.
Furthermore, such configuration may be desireable to support ipvlan-like
configurations for RDMA CM with IPoIB. To resolve the device in these
cases the code will also take the IP address as an additional input.

An ib_client callback that is called with the lists_rwsem locked only for
read is protected from changes to the IB client lists, but not from
ib_unregister_device() freeing its client data. This is because
ib_unregister_device() will remove the device from the device list with
lists_rwsem locked for write, but perform the rest of the cleanup,
including the call to remove() without that lock.
Mark client data that is undergoing de-registration with a new going_down
flag in the client data context. Lock the client data list with lists_rwsem
for write in addition to using the spinlock, so that functions calling the
callback would be able to lock only lists_rwsem for read and let callbacks
sleep.
Since ib_unregister_client() now marks the client data context, no need for
remove() to search the context again, so pass the client data directly to
remove() callbacks.

Persuant to Liran's comments on node_type on linux-rdma
mailing list:
In an effort to reform the RDMA core and ULPs to minimize use of
node_type in struct ib_device, an additional bit is added to
struct ib_device for is_switch (IB switch). This is needed
to be initialized by any IB switch device driver. This is a
NEW requirement on such device drivers which are all
"out of tree".
In addition, an ib_switch helper was added to ib_verbs.h
based on the is_switch device bit rather than node_type
(although those should be consistent).
The RDMA core (MAD, SMI, agent, sa_query, multicast, sysfs)
as well as (IPoIB and SRP) ULPs are updated where
appropriate to use this new helper. In some cases,
the helper is now used under the covers of using
rdma_[start end]_port rather than the open coding
previously used.

For devices which support OPA MADs
1) Use previously defined SMP support functions.
2) Pass correct base version to ib_create_send_mad when processing OPA MADs.
3) Process out_mad_key_index returned by agents for a response. This is
necessary because OPA SMP packets must carry a valid pkey.
4) Carry the correct segment size (OPA vs IBTA) of RMPP messages within
ib_mad_recv_wc.
5) Handle variable length OPA MADs by:
* Adjusting the 'fake' WC for locally routed SMP's to represent the
proper incoming byte_len
* out_mad_size is used from the local HCA agents
1) when sending agent responses on the wire
2) when passing responses through the local_completions
function
NOTE: wc.byte_len includes the GRH length and therefore is different
from the in_mad_size specified to the local HCA agents.
out_mad_size should _not_ include the GRH length as it is added

Add OPA MAD support flags to the core capability immutable flags. In addition
add the rdma_cap_opa_mad helper function for core functions to use to detect
OPA MAD support.
OPA MADs share a common header with IBTA MADs but with some differences for
increased performance.
Sharing a common header with IBTA MADs allows us to share most of the MAD
processing code when dealing with OPA MADs in addition to supporting some IBTA
MADs on OPA devices.
OPA MADs differ in the following ways:
1) MADs are variable size up to 2K
IBTA defined MADs remain fixed at 256 bytes
2) OPA SMPs must carry valid PKeys
3) OPA SMP packets are a different format
The MAD stack will use this new functionality to determine if OPA MAD
processing should occur on individual device ports.

In order to support alternate sized MADs (and variable sized MADs on OPA
devices) add in/out MAD size parameters to the process_mad core call.
In addition, add an out_mad_pkey_index to communicate the pkey index the driver
wishes the MAD stack to use when sending OPA MAD responses.
The out MAD size and the out MAD PKey index are required by the MAD
stack to generate responses on OPA devices.
Furthermore, the in and out MAD parameters are made generic by specifying them
as ib_mad_hdr rather than ib_mad.
Drivers are modified as needed and are protected by BUG_ON flags if the MAD
sizes passed to them is incorrect.

timestamp_mask - how many bits are valid in the timestamp, where timestamp
values could be 64bits the most.
hca_core_clock - timestamp is given in HW cycles, the frequency in KHZ units
of the HCA, necessary in order to convert cycles to seconds.
