[Qemu-devel] [PATCH v3 1/2] rtl8139: Do not consume the packet during overflow in standard mode. |

When operation in standard mode, we currently return the size
of packet during buffer overflow. This consumes the overflow
packet. Return 0 instead so we can re-process the overflow packet
when we have room.
This fixes issues with lost/dropped fragments of large messages.
