    摘要: A LAN adapter for transferring data frames from a LAN to memory buffers in a processor in which the LAN driver follows either the ODI or the NDIS specification. The adapter accumulates the frame length and compares this to the storage capacity of the buffer. If the frame length does not exceed the buffer capacity and the LAN driver implements the ODI specification, the adapter will indicate good status to the driver. If the frame length exceeds the buffer capacity the adapter will either send bad status to the ODI driver or reuse the buffer and send no status. If the driver follows NDIS, status is sent at the end of the frame.
