As mentioned in
http://gitweb.dragonflybsd.org/dragonfly.git/commit/727ccde8cce813911d885b7f6ed749dcea68a886,
DragonFly BSD is dropping support for IPv6 IPv4-mapped address.
Unfortunately, on some released versions we see the kernels pretend to
support the feature but actually not (unless tweaking some kernel states
via sysctl.)
To avoid unpredictable behavior, the net package assumes that all
DragonFly BSD kernels don't support IPv6 IPv4-mapped address.
Fixes#10764.

Not only by network, transport-layer intermediaries but by
virtualization stuff in a node, it is hard to identify the root cause of
weird faults without information of packet flows after disaster
happened.
This change adds Source field to OpError to be able to represent a
5-tuple of internet transport protocols for helping dealing with
complicated systems.
Also clarifies the usage of Source and Addr fields.
Updates #4856.

Ideally, those methods should return a copy of the Addr, but
due to the Go 1 API guarantee, we cannot make that change now:
there might exist client code that uses the returned Addr as
map index and thus relies on the fact that different invocation
of the method returns the same pointer. Changing this behavior
will lead to hidden behaviour change in those programs.
Update #9654.
