I'm using the small implementation of the TSE MAC. I'm using it without NIOS. I'd like to send 64 bytes frame using the MAC crc computation (setting ff_tx_crc_fwd input to '0'). If I send 63 bytes to the MAC, the frame isn't send. So I send 64 bytes to the MAC, the frame is send with its CRC but, finally, the frame is 65 bytes long... I tried to disable MAC CRC computation, I sent 64 bytes to the MAC including the correct CRC and everything is fine. Any idea ? Thanks in advance, Franck.
