A CNI plugin that gives FreeBSD containers an address on a real LAN segment.

FreeBSD has no macvlan. This plugin does the native equivalent: it creates an
epair per container, attaches one end to a host bridge, moves the other into
the container's jail, and applies the address supplied by IPAM.

IPv4 and IPv6 are both supported, together or alone: a network configuration
carrying a range for each gives the container an address and a default route
in both families.

It implements the ADD, DEL, CHECK and VERSION commands, and delegates address
allocation to the IPAM plugin named in the network configuration.
