How about this for the FreeBSD related code?

The video recording of said = presentation is at https://youtu.be/La4ekkKbM5o and = slides are at https://papers.freebsd.org/2018/chittenden-freebsd_vpc.files/ch= ittenden-freebsd_vpc-slides.pdf

The presentation details enhancements = to FreeBSD, to allow efficient private networking between bhyve guests = as well as jails on overlay networks, running across separate FreeBSD = hosts. This, according to the presentation, comes in the form of a suite = of VXLAN-related network interfaces.

=46rom two of the slides:

vpc(4) = Interfaces
vpcsw(4) - switches packets - one packet = per customer, multiple subnets supported in the same switch
vmnic(4) - dedicated guest NIC, looks like a virtio network = device to guests
vpcp(4) - plugs vmnic(4) ports = into vpcsw(4) switches vpci(4) - Non-bhyve(4) interface, usable in = jails(2)
ethlink(4) - Performs unencapsulated = packet forwarding, wraps a cloned or physical ethernet = interface
vpclink(4) - Performs VXLAN = encapsulation

New System Calls
vpc_open(2) - Creates a new VPC descriptor vpc_ctl(2) - = Manipulates VPC descriptors Capsicum-like, intended for privilege = separation Intended for idempotent tooling
Makes = aggressive use of UUIDs as operator handles to be compatible with = Triton

At = the very end of the presentation slides are links to for kernel code and = kernel library code on GitHub:

https://github.com/joyent/freebsd/tree/projects/VPC

https://github.com/joyent/freebsd/tree/projects/VPC/libexec/go/= src/go.freebsd.org/sys/vpc

Unfortunately, the whole repository on = GitHub is gone. 404. And I couldn=E2=80=99t find any forks of it = either.

Does = anyone have a copy of the VPC branch that Joyent had in that = repository?

All = that seems to be left of the project on Joyent's GitHub is a separate, = archived repository https://github.com/joyent/freebsd-vpc that only has = code for a utility that would interact with the code from the = aforementioned now gone repository.
