Hi,

    I have a new question about EMAC1 driver. hrm pg.1893 states "The receive DMA transfers data to a buffer until the buffer is full or the end of  packet is received from the MTL. When the FD bit of a descriptor is set, the amount  of valid data in a buffer is accurately indicated by the buffer size field  (programmed in the EMAC_DMA[n]_RXCTL registers)  minus the data buffer pointer offset. " But EMACPhyLoopback example does not consider buffer pointer offset, should this point be considered in usage?
