dhcpv6 README for the prototype release

this version is only for developers NOT for endusers!

you'll need:

redhat 7.1 for both client /server
interface eth0 set up for ipv6

install:

untar the package
server: copy config/dhcpd.conf to /etc/dhcpd.conf
client: copy config/dhcp-client_6 /sbin
do changes in *develop vars* at the end of includes/dhcp.h 
when compiling 
there are some warnings, und the relay dont compile
its ok.
server: run work-linux.../server/dhcpd -d -f
client: run wo.........../client/dhclient -d


the program

at first it was a bad idea to enhance isc dhcpv3,
I was wasting a lot of time for understanding the callback
structure.
the server should work normally as dhcpv4 server with
dhcpv6 enhancements the client are works only as dhcpv6 client.
this version is a snapshot from development. 
all code from me is sigend with /* rme */

what works :
client send solicit with duid und ia option 
server find lease an answer with ia option
client can select different adverts with the prefere value
client requests the advertised ia
server reply the ia
client binds to interface and write it down
dad
decline

the IA structure has to represent with IAD and all addresses
lifetimes of address in the ia has to looked up
CONFIRM / RENEW
general interface handling and looking for the ipv6 addresses
is now done with /proc/if:: lookups

improvements / contribs are welcome!
