Wanpipe is sharing interrupt

Hi,

i have got an issue. On my system wanpile is sharing interrups. when I run command “cat /proc/interrupts”, the out put contains:-
22: 8078117 0 0 66 Phys-irq peth0, wanpipe1, wanpipe2, wanpipe3, wanpipe4

it shows that wanpipe is showing interrupt with petho. Secondly uptill now I have seen that wanpipe normally uses interrupt 16 but here it is using 22. is this ok?
does any one knows how to resolve this?
