cb42705792 IB/hfi1: Add functions to parse 9B headers
These inline functions improve code readability by
enabling callers to read specific fields from the
header without knowledge of byte offsets.

37aab620bc IB/hfi1: Fix trace of atomic ack
The length is incorrect, causing the trace data to
be truncated.

Add the additional 8 bytes that should have been there.
Also trace out the atomic ack in hex to aid debugging.

261a435184 IB/qib,IB/hfi: Use core common header file
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

f48ad614c1 IB/hfi1: Move driver out of staging
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.
