The IRQ distribution should be checked on a multi-processor system. I typically have 3 Sangoma 
cards in low end Xeon servers and there aren't any problems.

Recently, I needed to patch irqbalance to evaluate the numa node values because some somewhat 
older versions of CentOS (6.3, 6.4 initially) do not set certain links inside sysfs. If there is 
some interest, I could publish my small patch.
