ohh, and a bonus idea, so if they support tofino2 emulation, then the you
should consider also tofino[1|2]_[veth|ext] modes too.... :)

another idea, you support now onie_machine=model in /etc/machine.conf
please consider splitting it to two... let's say model_veth where the current
functionality would be exposed, and model_ext where you dont spin up the veth
creation but start with an external port map exposing the vm physical
interfaces...
this way one could drop the image to gns3 and surround it with other boxes...
this is how i start my dataplane vm:
https://github.com/rare-freertr/freeRtr/blob/master/misc/p4bf/r1.sh
https://github.com/rare-freertr/freeRtr/blob/master/misc/p4bf/r2.sh
https://github.com/rare-freertr/freeRtr/blob/master/misc/p4bf/ports.json
just a small explanation, so in my port-map, ens4 = portid64 is the cpuport...
for a fully functional rare box, you still would need to create a single veth
pair,
one given as portid64 to tofino and the other side given to the freerouter as
cpuport...
