New release for uDAPL 2.0 available on the OFA download page and in my git tree.

New UCM provider uses it's own CM protocol on top of IB-UD queue pairs.
During device open, this provider creates a UD queue pair and
returns local address information via dat_ia_query. This 24 byte
opaque address must be exchange out-of-band before connecting to a
server via dat_ep_connect. This provider is targeted for MPI
implementations that already exchange address information
during boot/init phase and offers better scaling then existing 
scm and cma providers.
