Coldfire mcf52254 FEC drops a Tx packet

Dear Freescale,


Our processor fails to send  a packet, and at about the same time, fails to receive a ethernet packet.  It seems to be timing related.  We checked the error flags all the way down to the hardware level, all indications are that there was no error.  The first packet goes out but the second sent very quickly thereafter does not go on the wire (according to WireShark).


The forums talk about sending duplicate packets, but I have not found anything discussing missing packets.  Is there anything you are aware of in an addendum somewhere?
