MacOS X implementation of the Mirage NETWORK interface

mirage-net-macosx -- MacOS X implementation of the Mirage NETWORK interface.

This interface exposes raw Ethernet frames using the Vmnet framework that is available on MacOS X Yosemite onwards. It is suitable for use with an OCaml network stack such as the one found at https://github.com/mirage/mirage-tcpip.

limitations

The backing Vmnet.framework supports only IPV4 over DHCP, and does not allow for static configuration. mirage-net-macosx therefore must have access to a DHCP server in order to get a working network configuration, and unikernels built using mirage-net-macosx must be configured with --dhcp=true.

where it fits

For a complete system that uses this, please see the MirageOS homepage.

Inconsistent assumptions over interface Netif

Tried to make main.ml, using a fresh install of Mirage on Ocaml 4.02.01 (fully up to date) on OS X.10. Failed due to inconsistent assumptions, have dumped the terminal output here.

pls release

according to @thornleyk in ocaml/opam-repository#5808 (comment) this package needs a release (and previous releases need adjustments) -- I see that @samoht did remove the camlp4 earlier (thus master should work with an up to date sexplib)

Invalid_argument Cstruct.set_len

I'm seeing what seems to be an infinite loop with the following logs:

doesn't work with static IP address

Seems that only DHCP works.
