echo 9000 > /sys/class/net/eno16777736/mtu
Successful, even if the value is large.

Please tell me what is the necessity to set the mtu value?

[root@root ~]# ifconfig eno16777736 mtu 1600

大家讲道理

Is it because of the kernel? I am using the Linux 2.6.27 kernel. The MTU of each network has a maximum value. I checked that the MTU of 2.6.18 ib can be set to 65520, but it does not work under the 27 kernel.
