[ofa-general] uDAPL libdat2.so version [PATCH] udapl v1 and v2 - dat_create_psp_any() seed value wrong

[Tang, Changqing]

I am testing OFED 1.3 udapl v1, I have three nodes, n1, n2, and n3,
if I run two ranks between n1 and n2, it works, n2 and n3, it works again,
but if I run between n1 and n3, it fails with:

dat_cr_accept() failed: DAT_INTERNAL_ERROR

What could be the reason ? I did not change anything else except the
node to run. Thanks for help.
