- Basically this is porting docker PR #9381 to libnetwork - Added a Config.Validate() method where to consolidate a priori validation of bridge configuration - Have bridgeInterface store the current v4/v6 default gateways - Introduced two setupStep functions to set the requested def gateways Signed-off-by: Alessandro Boch <aboch@docker.com>
