Set IPv6 interface identifier

[fxp555]

Since it seems UNRAID OS is generating IPv6 interface identifiers randomly (if not let me know how these are actually generated) it would be very nice to add the possibilities to:

1) set the IPv6 address freely (already there)

2) use/enforce DHCPv6

2) use/enforce SLAAC but allow

    2.1) setting the interface identifier accordingly to EUI-64

    2.2) set tokenized interface identifiers (see man-pages)

    2.3) setting the interface identifier randomized

append a line in file:"config/go" , "/bin/sh /boot/cnofig/modify_dhcpcd.sh"

#!/bin/bash
# filename: config/modify_dhcpcd.sh
# usage: unraid-6.8.2 , modify dhcpcd.conf , duid
#      set SLAAC ipv6 in eui64, use own DUID.
#   create by yourself:"config/duid" (DUID) -> "05:0a:0c:12:13:14:15:16"
/bin/cp /boot/config/duid /var/lib/dhcpcd/duid
/bin/sed -i 's/^#slaac hwaddr/slaac hwaddr/g;s/^slaac private/#slaac private/g' /etc/dhcpcd.conf
if [ -f /run/dhcpcd-br0-6.pid ]; then
   kill $(cat /run/dhcpcd-br0-6.pid )
   dhcpcd -b -q -t 10 -h my_Tower_Name -C resolv.conf -6 br0
fi
