In case of point-to-point, you can set the checksum offload flag
VNET_HW_INTERFACE_FLAG_SUPPORTS_TX_L4_CKSUM_OFFLOAD when you create demo
interface.
And need to calculate ip4_hdr_checksum in your tx node
(ethernet_demo_device_class) if packet comes with
VNET_BUFFER_F_OFFLOAD_IP_CKSUM set.
I hope that it will resolve your problem.

I use demo.c create a interface demo0 with ip 10.0.0.1/29, and then use
vcl+iperf3 connect server ip 10.0.0.11, and then the ASSERT crash happend.
VPP start command: vpp -c as-startup-de192.conf
iperf3 start command:
sudo env \
LD_LIBRARY_PATH=/home/dev/code/net-base/dist/script/../lib: \
VCL_CONFIG=vcl-as-e18f7.conf \
LD_PRELOAD=/home/dev/code/net-base/dist/script/../lib/libvcl_ldpreload.so \
iperf3 -4 -c 10.0.0.11 -p 1000 -t 30
