Abstract:
A network interface comprising:a media access controller (MAC) configured for transmitting a selected frame data from data memory; a memory control unit configured for determining the status of the selected frame data; a descriptor management unit configured for reading and interpreting a descriptor associated with the selected frame data and containing a termination field containing information indicating if the selected frame data is to be deleted, and further configured to cause the MAC to append an inverted frame check sequence to the selected frame data when the selected frame data is to be deleted and transmission of data has already been initiated by the MAC, or delete the selected frame data from the data memory when the transmission of the selected frame data has not been initiated and the selected frame data is to be deleted, the inverted frame check sequence being an inversion of the frame check sequence that would be appended to the selected frame data when the selected frame data is not to be deleted.
