Subject: Allow to clear extra routes in NVP
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=0f129121a1c8331c702204cf95951444ae53ef9c;p=openstack-build%2Fneutron-build.git

Allow to clear extra routes in NVP

Since the neutron client can unset any attribute, ensure
we can handle empty routes as a way to clear the extraroutes
for the router.

Fixes bug #1202890
