Previously the E1000 network adapter would stop receiving further packets when an RX buffer overrun occurred. This was the case when connecting the adapter to a real network where enough broadcast traffic caused the buffer to be full before the kernel had a chance to clear the RX buffer.
This also updates the E1000 module to use macros instead of hard-coded magic values.
Further it adds logging for E1000 RX buffer overruns and avoids resetting the IRQ mask on each interrupt.
