Subject: [ofa-general] RDMA IOV segment limit is always zero?
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"
