问题
I m running iperf between two machines (linux) and I can observe the mtu of both the interfaces connected is 1500.
I ran tcpdump to capture packets and I observed some packets have "length as 2962"....how come this is possible with mtu as only 1500?
Please clarify. Thanks!
Note: flags field is set as DF. and proto is TCP

Turning off gso (in linux) did the trick
