Hello,
I want to count the number of times I reach an NIC receive interrupt.
I added a global static variable of type int , and initialized it to 0 ; each time I am in the rx_interrupt of the card I incerement it by one; I got large , non sensible numbers after one or two seconds;
So for debug I added printk each time I increment it in rx_interrupt.
What I see is that there are unreasonable jumps in the number
for instance , it inceremnts sequntially from 1 to 80,then jums to 4500, increments a little sequentially to 4580, and the jums again to 11000 ;
Is it got to do with it that this is in interrupt? Any idea what it can be ?
(I also tried to declare it as static in the rx_interrupt method and the same happened)
Thnx, John
