[RFC 0/9] bonding support

[Thomas Graf <tgraf redhat com>]

This is a first RFC post implementing bonding support in NM. It's not yet
complete but functional on my system.

Requires libnl-3.2.1

Details
  o both master and slaves require a ifcfg file:
     o master:
         TYPE=bond
	 DEVICE=bond3
	 BONDING_OPTS="mode=..."
     o slaves:
         TYPE=Ethernet
         MASTER=bond3

  o both master and slaves will have their own connection, creation
    of a new master connection of type "bond" trigger creation of
    virtual in-kernel interface if it does not exist yet.

  o activation of slaves is postponed until a connection is present
    with matching DEVICE= config

  o slave connection get no ip4/ip6 config but get a special "disabled"
    ip4 config added in order not to trigger dhcp on the slaves.

  o upon activation of slave, slave is enslaved to master using libnl3
    or if kernel does not support it yet, using ioctl()

  o There is no NMDeviceBond, NMDeviceEthernet is reused since a bond
    is basically an ethernet device. Good idea?

  o "master" property of all slaves return "bond0", "bond3", ...

  o TODO: The bond connection does not wait with ip config until all
          slaves have activated yet. Not sure how to implement this
	  properly yet.

  o TODO: "slaves" property still missing

  o TODO: Proper GUI integration

  o TODO: Naming of slave connections to display their relationship to
          a slave.

Thoughts?

Thomas Graf (9):
  bonding: settings parser for ifcfg plugin + NMSettingBond class
  bonding: bonding master device creation
  bonding: Detect virtual bonding devices and create an ethernet device
  ethernet: Correctly match bonding ethernet devices with bonding
    connection
  connection-setting: implement ability to define a master connection
  device: Postpone auto-activation of a  slave until its master is
    present
  device: Add "master" property to provide a reference to the master
    link
  ifcfg: Ignore higher level configs for bonding slaves
  device: Enslave/release a link before bringing it up/down if belongs
    to a master
