From 635126b7ca13a01d6322fbf7bdc5d1c738d26807 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Fri, 12 Sep 2014 16:26:17 -0400 Subject: [PATCH] bridge: Allow clearing of pvid and untagged bitmap Currently, it is possible to modify the vlan filter configuration to add pvid or untagged support. For example: bridge vlan add vid 10 dev eth0 bridge vlan add vid 10 dev eth0 untagged pvid The second statement will modify vlan 10 to include untagged and pvid configuration. However, it is currently impossible to go backwards bridge vlan add vid 10 dev eth0 untagged pvid bridge vlan add vid 10 dev eth0 Here nothing happens. This patch correct this so that any modifiers not supplied are removed from the configuration. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
