Subject: [PATCH 05/17] fipvlan: start VLAN interface from netlink handler
|
|
|
|
Instead of starting the VLAN interface after the call to
|
|
vlan_create() we should rather start it after the netlink
|
|
message has been received. Otherwise we have a race window
|
|
as we might try to start a network interface which isn't
|
|
present yet.
