Is It a DMA Adapter?

We suspect that the network card had been configured in such a way that it was eventually like pooping some packets into the space or something. But certainly we just refused to ever use those physical pages ever again. It's not like it was our fault. So like, it must have been DMA from outside the CPU. And because like, the firmware is gone at this point,. It's not running anymore. So it's not running in air. We don't want it to be running in any way we can tell."
