4.1.4.8. Frame Writing

The IP removes the preamble and SFD fields from the frame. The CRC field and padding bytes may be removed depending on the configuration.

For MAC variations with internal FIFO buffers, the MAC function writes the frame to the internal receive FIFO buffers. For MAC variations without internal FIFO buffers, it forwards the frame to the Avalon® streaming receive interface.

MAC variations without internal FIFO buffers do not support backpressure on the Avalon® streaming receive interface. In this variation, if the receiving component is not ready to receive data from the MAC function, the frame gets truncated with error and subsequent frames are also dropped with error.
