The ib_write_bw test allows using up to 16384 QPs. When a relatively
large number of QPs (within that range) is used, the test can fail
because the number of CQ entries needed exceeds the limit set by the
driver.
This patch increases the default setting of max_cqes from 0x2FFFF
(196607) to 0x2FFFFF(3145727), which is sufficient to cover the
maximum number needed by the ib_write_bw test (2097152). The default
setting of max_qps is also increased from 16384 to 32768 to allow
the test to run successfully with 16383 or 16384 QPs.

Use common header file structs, defines, and accessors
in the drivers. The old declarations are removed.
The repositioning of the includes allows for the removal
of hfi1_message_header and replaces its use with ib_header.
Also corrected are two issues with set_armed_to_active():
- The "packet" parameter is now a pointer as it should have been
- The etype is validated to insure that the header is correct

Pull second round of rdma updates from Doug Ledford:
"This can be split out into just two categories:
- fixes to the RDMA R/W API in regards to SG list length limits
(about 5 patches)
- fixes/features for the Intel hfi1 driver (everything else)
The hfi1 driver is still being brought to full feature support by
Intel, and they have a lot of people working on it, so that amounts to
almost the entirety of this pull request"

In order to support extended memory management support, add send side
processing of work requests of type IB_WR_REG_MR, IB_WR_LOCAL_INV, and
IB_WR_SEND_WITH_INV. The first two are local operations and are supported
for both RC and UC. Send with invalidate is only supported for RC because
the corresponding IB opcodes are not defined for UC.

The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
