How to give highest priority to ethernet interrupt in linux

I listed all interrupts with this:

cat /proc/interruts

it gives this:

        CPU0        CPU1         CPU2        CPU3
    0:   126           0            0           0     IO-APIC-edge        timer
    1:   941           0            0           0     IO-APIC-edge        keyboard
    ... (etc.)
   19:   941           0            0           0     IO-APIC-fasteoi      eth0
    ... (etc.)

Does the first column in this table give priority level of interrupts? I just want to learn priority levels, because I want to increase my NIC's interrupt priority level for better network performance. I think, first two interrupts cannot be changed (I guess due to intel x86 architecture).

Anyway, here is my question:

Is it possible to increase priority level of my NIC's interrupts?
