[j-nsp] Interrupt in Routing Engine

[Josef Buchsteiner]

in  addition  to  the  given answers 'vmstat -i' will give you how the
interrupts rate for the system.

<-- example

% vmstat -i
interrupt      total      rate
ata0 irq14       8629        0
fxp0 irq9      180826       15
fxp1 irq10      42179        3
sio0 irq4         218        0
clk irq0      1183640       99
rtc irq8      1515190      127
Total         2930682      247
