network protocol interrupts

hi

I was in little confusion about how the network software interrupts
actually work.

Is there a priority level within the network software interrupts too??

If there are two or more network level interrupts ( same priority level
splnet) are pending, then does the scheduler schedules them in the order
they were queued, or in the order they appear in the "netisrs" array.

for example,
the ip routine is defined as
#define NETISR_IP       2

and polling callback as
#define NETISR_POLL      0

and these are subscript of the array "netisrs".


Can somebody please explain that.

thanks
vaibhave
