From 3a7bde55a11c4a22a6ccfc487993d621ae8e3688 Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Wed, 28 Oct 2015 23:17:30 -0700 Subject: switchdev: fix: erasing too much of vlan obj when handling multiple vlan specs When adding vlans with multiple IFLA_BRIDGE_VLAN_INFO attrs set in AFSPEC, we would wipe the vlan obj struct after the first IFLA_BRIDGE_VLAN_INFO. Fix this by only clearing what's necessary on each IFLA_BRIDGE_VLAN_INFO iteration.
