Specify a minimum migration ratio to trigger a rebalancing
Normally any improvement in load distribution will trigger the migration of an
irq, as long as preforming the migration will not simply move the load to a new
cpu. By specifying a migration value, the load balance improvement is subject
to hysteresis defined by this value, which is inversely propotional to the
value. For example, a value of 2 in this option tells irqbalance that the
improvement in load distribution must be at least 50%, a value of 4 indicates
the load distribution improvement must be at least 25%, etc
