[openib-general] vapi versus openib imm_data

[Pete Wyckoff]

I have an application (PVFS2) that can use either VAPI (ibgd-1.8.2)
or OpenIB (libibverbs-1.0.3.1.fc4 and libmthca-1.0.1.fc.4).  Things
work just fine between one machine using VAPI and another using
OpenIB, but immediate data in an RDMA write comes through
byte-swapped.  Both ends are x86_64 hosts.

I'm using a heuristic now, knowing the range of values that are
valid, but is there any good way to tell if the other side has put
its imm_data in network byte order or not?
