Problem Description: 

Bugid: 1143975

Systems hang and/or crash with NC400 configured itself down.
The problem was caused by the cisco router that was broken and was
generating 1600 byte Ethernet packets. The NC400 fireware did not
check to make sure that the Ethernet packet was less than or equal 
to the Ethernet MTU. This resulted in firmware memory corruption 
that lead to a system panic.
