Doc Text:
While bringing down an interface, the e1000 driver failed to properly handle IRQs (Interrupt Requests), resulting in the reception of the following messages: irq NN: nobody cared... With this update, the driver's down flag is set later in the process of bringing down an interface, specifically, after all timers have exited, preventing the IRQ handler from being called and exiting early without handling the IRQ.
