From: Miguel Angel Ajo Date: Fri, 19 Jun 2015 14:43:52 +0000 (+0200) Subject: Introduce the AFTER_READ callback for ports and networks X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=e3dba1424114575581c153e02227282e036ad0a2;p=openstack-build%2Fneutron-build.git Introduce the AFTER_READ callback for ports and networks This callback can be used by extensions and service plugins to extend port and network information on read time, without the need of plugin mixins.
