[realtek] eth0: oversized ethernet farme a3ffffff

[ben]

when moving failry heavy loads the enternet stops with the following messages:

eth0: oversized ethernet farme a3ffffff

and :

4 errors 4 overruns 4 frame

The inteface works on software level, ie you can ping its IP number but no 
the other machines. Downing and upping the inetface makes it go again.

Thanks in advance for your help
