What I believe happens is that when the RX overflow condition occurs, there will be some packets that will be corrupted as a result. I find it really odd that you can reproduce this condition so readily. Does it happen under normal usage or do you have to issue a ping flood or some other packet intensive job to trigger the problem? Also, are you getting Pause enabled on the link consistently?
