Di Zhu 57fb346cc7 ipvlan: Add handling of NETDEV_UP events ... When an ipvlan device is created on a bond device, the link state of the ipvlan device may be abnormal. This is because bonding device allows to add physical network card device in the down state and so NETDEV_CHANGE event will not be notified to other listeners, so ipvlan has no chance to update its link status. The following steps can cause such problems: 1) bond0 is down 2) ip link add link bond0 name ipvlan type ipvlan mode l2 3) echo +enp2s7 >/sys/class/net/bond0/bonding/slaves 4) ip link set bond0 up After these steps, use ip link command, we found ipvlan has NO-CARRIER: ipvlan@bond0: <NO-CARRIER, BROADCAST,MULTICAST,UP,M-DOWN> mtu ...> We can deal with this problem like VLAN: Add handling of NETDEV_UP events. If we receive NETDEV_UP event, we will update the link status of the ipvlan. Signed-off-by: Di Zhu <zhudi21@huawei.com> Signed-off-by: David S.
