IPv6 Not working AC5300

[armsAC3100]

IPv6 stopped working on my 87U with Rogers. I can confirm that the following resolve the IPv6 problem with the current alpha firmware. IPv6 with Rogers has been working flawlessly with previous firmwares.

# Working
odhcp6c -df -R -s /tmp/dhcp6c -N try -c 00030001000000000001 -FP 0:ae57a -r82 -r83 eth0

Works for my AC3100 / SB6190 / Comcast network every time.
Not being a competent Linux programmer I am not sure how to create and add a script to automatically invoke each restart.

Changing the client is works for me as well.

Can anyone give me instructions on how to change my Client ID so I can get my IPv6 working again on my AC5300? Thank you
