What parts of the MAC frame must be loaded in the transmit buffer?
Format of the transmit buffer inside chip is given below : DestinationAddress-SourceAddress-Type/Length_Field-Data-CRC32 However, this is taken care of by the software-driver (for STE10/100A), which does PCI-transactions – to load transmit buffer inside chip from packet in PC-memory. Please refer to STE10/100A datasheet for further information.
