Hi,
I am confused with this in dmesg
*dmesg |grep "mtu"*

All interfaces are configured with MTU of 1500 (netstat -i )and on physical
switch also it is 1500.
I dont understand why it is showing above in dmesg,can some one explain me
why something is trying to send Frames above 1500 and getting blocked by
ovs,even if no interface has an MTU of 1500 < .Is there any way to find out
what is trying to send frames larger than 1500.
