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.

How big are the writes to the tx fifo? Make sure the tx buffer is some tens of
kB.

as mentioned in [1].
On the similar topic; the UDP tx
