Arista EOS MTU Behavior (3) - L3 Routed Ethernet Ports, IPv4

Now we switched to L3 routed ethernet (IPv4) ports:

• MTU enforcement is for egress traffic
• Hardware programs the MTU value (default value is 1500, in this case, 2000) and checks against forwarding packet length (in this case, it is ipv4 packet). 
• For IPv4 packets, if the length is more than MTU, the packets will be fragmented by CPU. 
• And the number of fragmented and dropped packets are reflected by CoPPEgressTrap counter in the output of "show cpu counters queue summary | nz"
