[PATCH 0/5] vlan support for NetworkManager(V2)



This patchset is to add vlan support for NetworkManager,
based on nm/bonding branch, commit 6b1d0ca510d2(bonding:
don't fall back to DHCP if IP config is missing).

Requires libnl-3.2.1

FEATURE DESCRIPTION
1 example of vlan ifcfg file
We try to make it compitable with the format used by initscripts,
and there is no need to change anything for ifcfg-eth9.

vlan=yes
TYPE=vlan
DEVICE=vlan43
PHYSDEV=eth9
REORDER_HDR=0
vlan_FLAGS=GVRP,LOOSE_BINDING
vlan_INGRESS_PRIORITY_MAP=0:1,2:5
vlan_EGRESS_PRIORITY_MAP=12:3,14:7
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.43.149
NETMASK=255.255.255.0

2 create and delete vlan device
We use libnl to create and delete vlan device in kernel.

3 support both static IP configuration and DHCP for vlan device

TODO
1 accept MAC address or NM connection UUID as PHYSDEV

2 activating dependency
Before activating a vlan device, we should make sure that the underlying
physical ethernet device is up.
For example, before activating eth0.100, we should make sure that eth0 is up.
NetworkManager calls g_udev_client_query_by_subsystem() to get the device
list, and then activates each devices on that device list.
And luckily I found that the physical ethernet device is prior to vlan device
on that device list, so there is nothing to do to make sure the activating
sequence between a vlan device and its underlying physical ethernet device.

Maybe we should not rely on the behavior of
g_udev_client_query_by_subsystem(), and we should add special restriction to
make sure that before activating a vlan device, the underlying physical 
ethernet device is up.

Changelog:
V2:
1 rebase on nm/bonding branch
2 use "vlan" or "Vlan" instead of "VLAN" for consistency.
3 use GSList to store vlan ingress/egress priority map.
4 add enum NMVlanFlags.
5 delete NMDeviceVLAN, just use NMDeviceEthernet.
6 add ifcfg-vlan writer

Weiping Pan (5):
  configure: use correct if defined
  vlan: add ifcfg-vlan parser
  vlan: create/delete kernel vlan device
  vlan: create NMDeviceEthernet for vlan device
  vlan: add ifcfg-vlan writer
