Yes, this will work. The uDAPL support in MVAPICH/MVAPICH2 works well
with any uDAPL layer (including that of OFED). In fact, during every
release, we carry out extensive test of the uDAPL interface over OFED
uDAPL.

You can also find this information in the user guides (available from
mvapich web site).
