I have a namespace connected to ovs-dpdk via a tap device
# create an internal ovs port
ovs-vsctl add-port br-int tap1 -- set Interface tap1 type=internal
# attach it to namespace
ip link set tap1 netns ns1
I also have vxlan port in the br-int.
When I send a packet from namespace with len=2000, I see in the namespace that a packet with len 2000 isi transmitted but in the vxlan port statistics I see that the packet is received with 1500 bytes only.
Why/where is this packet truncated ? all my interfaces are set with MTU 9000
When connected via veth-pair pkt are OK.
