Sean,

I noticed that in this update to librdmacm, you added functionality (to the 
ABI).

Should we use this revision (6949/6950 of the openib trunk) of the rdma_cm in 
the upcoming OFED (branch) release? 

If yes, I will update both the kernel and userspace rdma_cm (in the branch) 
for OFED RC5.

If not, please change the trunk ABI version (RDMA_USER_CM_ABI_VERSION) to 2 in 
file 
   linux_kernel/driver/infiniband/include/rdma/rdma_user_cm.h 

(since the branch rdma_cm kernel module will be in the field -- and it will 
not support the get/set transport-specific options),

and also change RDMA_USER_CM_MAX_ABI_VERSION to 2 in userspace file 
rdma_cma_abi.h, and add appropriate kernel abi version checking in userspace 
for the userspace functions unavailable with a kernel rdma_cm module which 
supports only ABI version 1.
