The transmitting network device is specified via the destination
address, not the source address.  There is no reason to set
sin6_scope_id on the source address.

Update the DNS resolver to support DNS search lists (as provided by
DHCP option 119, DHCPv6 option 24, or NDP option 31).

Add validation code to ensure that parsing of DNS packets does not
overrun the input, get stuck in infinite loops, or (worse) write
beyond the end of allocated buffers.

Allow for IPv6 routing table entries to be created for an on-link
prefix where a local address has not yet been assigned to the network
device.

Add support for the stateful and stateless variants of the DHCPv6
protocol.  The resulting settings block is registered as
"net<x>.dhcpv6", and DHCPv6 options can be obtained using
e.g. "${net0.dhcpv6/23:ipv6}" to obtain the IPv6 DNS server address.

IPv6 addresses obtained via stateful DHCPv6 are not yet applied to the
network device.

Include IPv6 within the generic network device configurator
mechanism.  The IPv6 configurator will send a router solicitation and
wait for a router advertisement to be received.  (As per RFC4861
section 6.3.7, we do this even if advertisements have been received
prior to sending the router solicitation.)

sin6_scope_id is never exposed outside of the local system, and so
should be a native-endian quantity.

Fix uninitialised-variable warning reported by gcc 4.5.2.

Replace the existing partially-implemented IPv6 stack with a fresh
implementation.

This implementation is not yet complete.  The IPv6 transmit and
receive datapaths are functional (including fragment reassembly and
parsing of arbitrary extension headers).  NDP neighbour solicitations
and advertisements are supported.  ICMPv6 echo is supported.

At present, only link-local addresses may be used, and there is no way
to specify an IPv6 address as part of a URI (either directly or via
a DNS lookup).

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain.  Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.

Also update README, LOG and COPYRIGHTS to remove obsolete information.

is non-functional anyway.

Achieved via Perl using:

perl -pi -e 's/pk_buff/io_buffer/g; s/Packet buffer/I\/O buffer/ig; ' \
	-e 's/pkbuff\.h/iobuf.h/g; s/pkb_/iob_/g; s/_pkb/_iob/g; ' \
	-e 's/pkb/iobuf/g; s/PKB/IOB/g;'

defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.
