Subject:   Polling mode vs. net.isr.enable

Does the value of net.isr.enable (0 or 1) have any effect when running an
interface in polling mode?

If I understand correctly, with net.isr.enable set to 1 the processing of
incoming packets are handled directly in the ISR (interrupt service
routine?) instead of being deferred to the ithread. However, polling mode
means no interrupts so the ISR is never called(?).
