Looks like either the receiver or the sender is inserting two bytes 
with all bits set at the beginning of some frames.  Let me guess: this 
concerns port 1/8 on your XMR?  That's not legal Ethernet, though, as 
your wireshark dump already shows (frame length of 1).

I've not seen this particular failure mode myself but I hope that 
doesn't say too much. :) I'd try switching ports and if possible 
linecards on both sides, see if the problem goes away after doing one 
action at a time, and send the broken hardware back to the vendor 
after isolating.
