Why is em nic generating interrupts?
Hello, everyone! I've got a [uniprocessor] router machine with fxp and em nics. I've built my kernel with the following included: options DEVICE_POLLING options HZ=2500 and enabled polling in /etc/sysctl.conf. Having looked through a vmstat -i output I see that the em card is generating interrupts, although they should be disabled (as I see in em's source code). interrupt total rate stray irq01 0 stray irq61 0 npx0 irq131 0 ata0 irq14 2339 0 em0 irq10421457155 fxp0 irq5 2 0 atkbd0 irq13326 1 clk irq06778872 2500 rtc irq8 346899127 Total 7552898 2786 What's happening? Is polling working in my case? If yes, why is vmstat showing interrupts? I see clearly, that fxp's counter doesn't increase, and em's is constantly growing. Thanks in advance to anyone for an idea!
