vlan: Fix register_vlan_dev() error path In case register_netdevice() returns an error, and a new vlan_group was allocated and inserted in vlan_group_hash[] we call vlan_group_free() without deleting group from hash table. Future lookups can give infinite loops or crashes. We must delete the vlan_group using RCU safe procedure. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
