[Bug 872935] [NEW] dual IPv4/IPv6 DHCP client gets DNS server wrong/missing

[Andreas Schultz]

Public bug reported:

current resolv.conf update code assumes that only the DNS server from the lastest DHCP answer is to be used.
That assumption is wrong in a dual IPv4/IPv6 DHCP setup. The IPv4 DNS server from the IPv4 DHCP answer and the IPv6 server from the IPv6 answer should both be kept.
