[ofa-general] uDAPL libdat2.so version # problem for today's OFED code

[Tang, Changqing]

Arlin:
        Thank you for pointing this out, I almost forgot this mismatch issue.

Here is the error we got when we port v1 code to v2, can you give some hint ?

setup_listener Permission denied
setup_listener Permission denied
setup_listener Permission denied
setup_listener Permission denied
setup_listener Permission denied
setup_listener Permission denied
....

I verified that rdma-cm works using 'rping' utility.
