[PATCH v2] tools: hv: kvp_daemon: make IPv6-only-injection work

From: Dexuan Cui
Date: Wed Dec 10 2014 - 05:23:15 EST


In the case the host only injects an IPv6 address, the dhcp_enabled flag is
true (it's only for IPv4 according to Hyper-V host team), but we still need to
proceed to parse the IPv6 information.

v2: removed the distro-specific logic as Vitaly suggested.
