 A relay with only IPv6 address(es) doesn't work for several reasons.
 That's OK for quite a while -- we probably don't want a network with
 relays which can connect only to a (smallish) subset of the other
 routers.

 But there are also limitations in the code today making a relay use
 the mandatory IPv4 address in ways it shouldn't have to.  An example
 is a bridge requiring that an IpV4 address is configured (but not
 necessarily being used) in order to work.

 This enhancement ticket collects the kind of bugs which are not
 strictly showstoppers for a mixed IPv4/IPv6 network to function but
 which should be fixed anyway.
