Fragmentation is expensive. Therefore, because tcp originates the packets
locally, we do not want it to exceed the interface’s mtu. If you want to force
larger bursts from tcp, try enabling tso if the egress interface supports it.
Any particular reason why you’d like tcp to use such a large
Hi guys,
In my project, I set tcp mtu 9000 in vpp startup file: tcp { mtu 9000 }, and
set interfaces mtu 1500. When sending tcp packet, vlib_buffer_push_ip4 will add
'dont frag' flag for packet, if tcp data more then 1500 bytes, i will "ip4 MTU
exceeded and DF set" error.
