VMA_RX_POLL=-1 VMA_SELECT_POLL=-1 with thread affinity

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I've three TCP sessions, each one have own receiving thread (non-blocking)
2. Each receiving thread have affinity set to the same CPU (i.e. all have 
cpumask = 3 for example)
3. VMA_RX_POLL=-1 VMA_SELECT_POLL=-1
4. Application is on SCHED_FIFO

What is the expected output? What do you see instead?

Seems like everything hangs. If I leave only VMA_RX_POLL=-1 then it might 
occasionally (very rarely) hang as well.

Is it possible to selectively apply different VMA_RX/SELECT_POLL to UDP and TCP?

What version of the product are you using? On what operating system?

VMA 6.6.4 OFED 2.2 RHEL 6.5
