The RealTek data sheets are of especially poor quality, and there is a lot of information missing particularly concerning the receiver operation. One particularly important fact that the data sheets fail to mention relates to the way in which the chip fills in the receive buffer. When an interrupt is posted to signal that a frame has been received, it is possible that another frame might be in the process of being copied into the receive buffer while the driver is busy handling the first one. If the driver manages to finish processing the first frame before the chip is done DMAing the rest of the next frame, the driver may attempt to process the next frame in the buffer before the chip has had a chance to finish DMAing all of it.
