	When I call dat_ep_query(), the max IOV segments for RDMA
read/write always is returned as zero.  I tried it on a couple different
adapters (Mellanox 26428  and 25204). Does the value zero mean something
else, like "unlimited"? I'm using DAT 2.0 and the code looks like this: 
	 
	Which provder are you using? Is this the new socket cm provider?

	 
	looks like the max_iov setting per rdma is not being set with
the new socket cm provider. I will fix this for OFED 1.4.
	

	
	You can get the device attributes with "ibv_devinfo -v"
