Subject: Allow default network and policy profiles
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=dc48ac1a9c02c236157347f715190a2b1107ec70;p=openstack-build%2Fneutron-build.git

Allow default network and policy profiles

Allow for default network/policy profile to be used if
no network/policy profile is specified during network/port creation
in the Cisco N1KV plugin.

Change-Id: I6120abb5abb9a869eb7310453cf27dd8f72bfd1d
Closes-Bug: #1218588
