[ofa-general] [PATCH] uDAPL v2: dapltest, adjust next port number for number of threads to avoid duplication

[Davis, Arlin R]

Arkady,

Actually, we encountered these problems running back to back multi-threaded transaction tests on Windows while trying to get to uDAPL 100% common code across Windows and Linux. Difference in schedulers bought out some of these problems along with extended runs with the server running continuously. We also run dapltest with multiple clients, one server, so we are pushing this pretty hard.

Arlin,
did we encounter this issue at interop?
I do not recall seeing it.
For IB, does Wait period between assigning the same QP# handles it?
Thanks,
Arkady

To avoid duplicating port numbers between different tests, the next port
number to use must increment based on the number of endpoints per thread *
the number of threads.
