[PATCH 2/4] netconfig: Remove IPv6 default route

[Tim Kourt <tim.a.kourt@linux.intel.com>]

[-- Attachment #1: Type: text/plain, Size: 1332 bytes --]

The IPv6 default route needs to be explicitly revoked. Unlike in IPv4,
there is no SRC address associated with the route and it will not be
removed on address removal.
