problem reported: kernel 4.1.3 ------------ # bridge vlan port vlan ids eth0 1 PVID Egress Untagged 90 91 92 93 94 95 96 97 98 99 100 vmbr0 1 PVID Egress Untagged 94 kernel 4.2 ----------- # bridge vlan port vlan ids ndo_bridge_getlink can return -EOPNOTSUPP when an interfaces ndo_bridge_getlink op is set to switchdev_port_bridge_getlink and CONFIG_SWITCHDEV is not defined. This today can happen to bond, rocker and team devices. This patch adds -EOPNOTSUPP checks after calls to ndo_bridge_getlink. Fixes: 85fdb956 ("switchdev: cut over to new switchdev_port_bridge_getlink") Reported-by:
