Some drivers queue these buffers in the hardware. When multiple of these drivers are active at the same time then they stamp over each others packets and bad things happen. The goal is to remove NetRxPackets[] entirely in favor of per device packet buffers. This series is a first step into that direction. It removes the simple cases where only NetRxPackets[0] is used to store the single packet that is pulled out of the hardware before net_receive() is called.
