[openib-general] [PATCH] cmpost: allow cmpost to build with latest RDMA CM

[Bub Thomas]

OK
Can I still use the LID, GUID and SubnetID for connection establishment
then? Then Gen1 counterpart has no IP over IB running.
I'm using OFED-1.0.1. 
Do you have a quick link where to find the latest Headers?
(Sorry for the dumb question)

Thanks
Thomas

The RDMA CM is only used on the local (active or client) side to obtain
a path 
record, which is needed by the libibcm.  Using the librdmacm allows
cmpost to 
get a path record given only the remote IP address or host name.

The connection is established using the IB CM through libibcm.

rdma_cm.h defines the kernel interface to the RDMA CM.  rdma_cma.h
defines the 
userspace interface.

Can you verify that you have the latest version of rdma_cma.h?
