18 should be OK I guess, unless you have congestion in your fabric, in
which case you have other problems anyway.

Is there a common recommended value for this timeout ? I use 18, which
represents 1 second.

Hi Dotan,
This may be a very basic question. When u said "QPs can listen/send the packets on any port and write to the same MR", does it mean QPs can listen/send packets to any port on the same HCA or to also ports on different HCA ?

Hi
I have two HCA cards each having one port. I want to use same memory buffer to store packets arriving on the two ports. Can I do this, meaning can I use same pd (protection domain) and mr (memory registration) for the two QPs (one QP on each port), though the context (
i.e. ib device) for each
