It does. But on the other hand interrupt handler may still be active. On linux for example the CPU is halted in the idle task, too. Therefore it will consume much less energy. Thats why you can even get ping replies if your kernel is in an endless loop, cause the incomming data and the irq from the card will interrupt its work and calls the bottom half handler. It's an error if the kernel forgets to unregister all those interrupt routines on halt, but its an understandable 'feature'. But it should NOT happen if you shut down the interface before halt (ifconfig down).
