an IRQ may be handled on any CPU. Because a non-negligible part of packet
processing takes place in receive interrupt handling, it is advantageous
to spread receive interrupts between CPUs. To manually adjust the IRQ
-affinity of each interrupt see Documentation/IRQ-affinity. Some systems
+affinity of each interrupt see Documentation/IRQ-affinity.txt. Some systems
will be running irqbalance, a daemon that dynamically optimizes IRQ
assignments and as a result may override any manual settings.
