From a6fde4aa02862f51cbd3618ade199c64915469d3 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sun, 24 Nov 2019 20:27:25 +0100 Subject: bridge: T1673: add missing VLAN bridge member migration VLAN interfaces assigned to a bridge as member have not been migrated so far. This was the case for vif, vif-s and vif-c interfaces. The migration code has been generalized in migrate_bridge() so it is re-usable for regular interfaces, vif, vif-s and vif-c interfaces - all now use the same code. --- src/migration-scripts/interfaces/0-to-1 | 171 +++++++++++++++++++------------- 1 file changed, 101 insertions(+), 70 deletions(-) (limited to 'src') diff --git a/src/migration-scripts/interfaces/0-to-1 b/src/migration-scripts/interfaces/0-to-1 index 96e18b5d5..a67a4a325 100755 --- a/src/migration-scripts/interfaces/0-to-1 +++ b/src/migration-scripts/interfaces/0-to-1 @@ -6,78 +6,109 @@ # https://phabricator.vyos.net/T1556 import sys -
