VLAN tagged interface is not being created as expected: Device ethX.X does not seem to be present, delaying initialization.

Issue

• A proper interface configuration file is in place to create a VLAN interface, but it is never created:

$ cat /etc/sysconfig/network-scripts/ifcfg-eth0.10
DEVICE=eth0.10
BOOTPROTO=static
IPADDR=192.168.100.1
NETMASK=255.255.255.0
ONBOOT=yes
VLAN=yes

# service network start
Bringing up loopback interface:  [  OK  ]
Bringing up interface eth0:  [  OK  ]
Bringing up interface eth0.10:  Device eth0.10 does not seem to be present, delaying initialization.   [FAILED]
