Our end2end DHCP solution is not yet working, but we need a way to
derive addresses for a BMC from the smart NIC in front of it. This
provides a mechanism for detecting the address from RA beacons the NIC
is sending.

We may have multiple BMCs running on the internal gbmcbr network via USB
links to attached trays. These BMCs do not have a direct connection to
the network, and require the NCSI BMC to relay all of their traffic
(including DHCP) out opf the machine. This patch enables dhcrelay to run
on the NCSI interface and proxy all DHCP traffic from the bridge out of
the machine.

We only want to allow <pfx>::fd... traffic info the machine area network
from the outside world. Instead of just blocking internal network
addresses from the outside, explicitly look at the prefix.

This allows gBMCs to route packets, needed for routing packets to the
management netowrk.

Break down packets by their incoming address and ensure that we don't
allow packets to unintended destinations. Right now this is effectively
a no-op, but it will be necessary for BMC public addressing.

Make it clear this is a gbmc style configuration, similar to
gbmc-systemd-config or gbmc-iperf3.
