See the DHCPv6_am, in the parse_options method, in there we need to know the interface information to compute the source ip address

[facetothefate]

are there any special reasons for delete those options ?

If you can test and confirm that this works, there is no problem to return these options. Must have been some reason for commenting out though at the time of porting, but nobody would recall.
