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 ?
 
Regards,
John T

if the context is different how can you create 2 QPs using the same PD?
The context is a driver abstraction and the HCA is not aware of it ...

anyway, if you have 2 QPs and 1 MR which are in the same PD, the QPs can
listen/send the packets on any port and write to the same MR
(in different address of course, the order of the packet arrival in
those QPs is "random" ...)
