the PCI ID. We'll put in the Intel values when we get them (may not
be for a few more weeks).

properly at all. NetEffect's current driver (OFED 1.4.0) will return
a CONNECT_ERROR event to the initiator rather than the REJECTED event.
Doh! Additionally -- unfortunately -- NetEffect's vendor_id and
vendor_part_id are reported as 0 in OFED 1.4.0, so we can't
automatically detect these cards and work around the problem. So all
we can do is add a new MCA parameter
(btl_openib_connect_rdmacm_ignore_connect_errors -- yes, it's long on
purpose ;-) ) that says that if we get a CONNECT_ERROR, bascially
treat it exactly as a REJECT for the WRONG_DIRECTION reason (which is
a "good" reject). This allows OMPI to function with NetEffect/Intel
cards on OFED 1.4.0.
Note that NetEffect has been bought by Intel; I'm waiting for
information from them to update the ini file for their new OUI/PCI
ID's and/or new vendor_part_id values.

<infiniband/driver.h> cannot be included because it will fail to
compile. So per advice from Roland, in that case, just put manually
include the one ibv_*() prototype that we need. Use an undocumented
feature of AC_CHECK_HEADERS to check for <infiniband/driver.h> that I
was told on the autoconf mailing list (see the comment for more
details).

THREAD_MULTIPLE. There's a new (hidden) MCA parameter to re-enable
these BTLs in the presence of THREAD_MULTIPLE:
btl_base_thread_multiple_override. This MCA parameter should ''only''
be used by developers who are working on make their BTLs thread safe;
it should ''not'' be used by end-users!

There is still a problem with OpenIB and threads (external to C/R functionality). It has been reported in Ticket #1539
Additionally:
* Fix a file cleanup bug in CRS Base.
* Fix a possible deadlock in the TCP ft_event function
* Add a mca_base_param_deregister() function to MCA base
* Add whole process checkpoint timers
* Add support for BTL: OpenIB, MX, Shared Memory
* Add support Mpool: rdma, sm
* Sundry bounds checking an cleanup in some scattered functions

I run IMB exchange on two QS22 machines with r19674 and it got stucked after 256 or 512 bytes every time.
After applying r19717 the test passed, so I guess this is a essential patch.
This commit was SVN r19752.

following names are all new for v1.3, and therefore haven't been
officially released yet:
* btl_openib_of_cq_size
* btl_openib_of_max_inline_data
* btl_openib_of_pkey
* btl_openib_of_psn
* btl_openib_of_mtu
The "_of_" (for OpenFabrics) in there is redundant. It used to be
"_ib_", indicating that these values are pretty much passed directly
to the verbs stack. But I think the "openib" in the name implies this
already; having "_of_" in there just seems redundant, makes the name
longer, and seems redundant. It's also redundant.
So I took those "_of_"'s out of the MCA names. The old (v1.2) names
are still valid (but deprecated), such ash btl_openib_ib_cq_size.
This commit was SVN r19718.
* Change name: mca_btl_openib_of_pkey_value -> mca_btl_openib_of_pkey
(since now there's no index, the "_value" suffix is somewhat
superfluous)
* Put in a better help message for the _pkey MCA param (to agree with
the new help message in v1.2.8)
This commit was SVN r19716.
Commit from a long-standing Mercurial tree that ended up incorporating a lot of things:
* A few fixes for CPC interface changes in all the CPCs
* Attempts (but not yet finished) to fix shutdown problems in the IB CM CPC
* #1319: add CTS support (i.e., initiator guarantees to send first message; automatically activated for iWARP over the RDMA CM CPC)
* Some variable and function renamings to make this be generic (e.g., alloc_credit_frag became alloc_control_frag)
* CPCs no longer post receive buffers; they only post a single receive buffer for the CTS if they use CTS. Instead, the main BTL now posts the main sets of receive buffers.
* CPCs allocate a CTS buffer only if they're about to make a connection
* RDMA CM improvements:
* Use threaded mode openib fd monitoring to wait for for RDMA CM events
* Synchronize endpoint finalization and disconnection between main thread and service thread to avoid/fix some race conditions
* Converted several structs to be OBJs so that we can use reference counting to know when to invoke destructors
* Make some new OBJ's have opal_list_item_t's as their base, thereby eliminating the need for the local list_item_t type
* Renamed many variables to be internally consistent
* Centralize the decision in an inline function as to whether this process or the remote process is supposed to be the initiator
* Add oodles of OPAL_OUTPUT statements for debugging (hard-wired to output stream -1; to be activated by developers if they want/need them)
* Use rdma_create_qp() instead of ibv_create_qp()
* openib fd monitoring improvements:
* Renamed a bunch of functions and variables to be a little more obvious as to their true function
* Use pipes to communicate between main thread and service thread
* Add ability for main thread to invoke a function back on the service thread
* Ensure to set initiator_depth and responder_resources properly, but putting max_qp_rd_ataom and ma_qp_init_rd_atom in the modex (see rdma_connect(3))
* Ensure to set the source IP address in rdma_resolve() to ensure that we select the correct OpenFabrics source port
* Make new MCA param: openib_btl_connect_rdmacm_resolve_timeout
* Other improvements:
* btl_openib_device_type MCA param: can be "iw" or "ib" or "all" (or "infiniband" or "iwarp")
* Somewhat improved error handling
* Bunches of spelling fixes in comments, VERBOSE, and OUTPUT statements
* Oodles of little coding style fixes
* Changed shutdown ordering of btl; the device is now an OBJ with ref counting for destruction
* Added some more show_help error messages
* Change configury to only build IBCM / RDMACM if we have threads (because we need a progress thread)

Ticket 1210 --> https://svn.open-mpi.org/trac/ompi/ticket/1210
(related to the presence of posix threads and ptmalloc2) is now a
little outdated: since we don't build ptmalloc2 as part of libopal
anymore, the openib BTL's requirements are not directly tied to
ptmalloc2's anymore. Specifically, I altered the test to:
1. At compile time, if no threads are found, the ptmalloc2 component
is going to be built, '''and the ptmalloc2 component is going to be
inside libopal,''' then refuse to build the openib BTL.
1. At run time, if no threads were available at compile time and the
ptmalloc2 component is part of the process, then refuse to use the
openib BTL.

figure it out at runtime (really meaning: we'll still default to "0"
unless something explicitly overrides to 1, such as the openib BTL).
This way, ompi_info doesn't confusingly report mpi_leave_pinned==0 for
mpi_leave_pinned, but we end up running with mpi_leave_pinned==1.

Roland noticed that the QLogic HCA driver was using the PCIe vendor ID
for the ibv_query_device so the IEEE OUI value is now used. This means
the config file should recognize the vendor ID value 0x1175 too.
