[LARTC] Ethernet card interrupt conflict

["yuxiao jia" <yxjia@site.uottawa.ca>]

Hello all

I install 4 ethernet card in my Linux router. When I use

cat /proc/interrupt      it show me two interface use same IRQ

...11:...........eth0 and eth2

I want to know how I can modify the eth0 to another unsued IRQ or avoid this
things happen

Thanks

Regrads
