I have OFED 1.3 and a Chelsio S310E-SR+ iWARP 10GE NIC. I have

How do I use uDAPL, though? All the default /etc/dat.conf entries
have IPoIB or bonding interfaces in them.
What you will want to do is edit /etc/ofed/dat64.conf or other
related dat.conf file and change the name of the device from "ib0" to
the name of the interface that the Chelsio card came up as. So for
example with my NetXen cards coming up at eth2, so for example the
first two lines of my /etc/ofed/dat64.conf file look like this:
OpenIB-cma u1.2 nonthreadsafe default /usr/lib64/libdaplcma.so dapl.
1.2 "eth2 0" ""
#OpenIB-cma u1.2 nonthreadsafe default /usr/lib64/libdaplcma.so dapl.
1.2 "ib0 0" ""
Notice how I've commented out the ib0 line and simply changed that to
be eth2. Then you can use say HP-MPI for example using the -UDAPL
option. Other MPI stacks have similar methods of telling them to use
the UDAPL transport.
