5482db8176 util: Remove NONNULL's for virNetDevVPortProfile[Associate|Disassociate]
The source code will check for NULL arguments for 'macvtap_macaddr' and
'vmuuid', so no need for the NONNULL in the prototypes. Following the stack
for both arguments to virNetDevVPortProfileOpSetLink also shows called
functions would handle a NULL value.

Additionally, modified the prototype to use the same 'macvtap_macaddr'
name as the source code for consistency.

e1f6485694 util: functions to support binding/unbinding midonet virtualports
Adds the port type definitions and methods that will be used to bind
interfaces to the Midonet virtual ports.

virtnetdevmidonet.c adds the way to bind and unbind the ports by
calling into the Midonet Host Agent control command line (installed
with the midolman package).

1b14c449b8 util: use typedefs for enums in "src/util/" directory
In "src/util/" there are many enumeration (enum) declarations.
Sometimes, it's better using a typedef for variable types,
function types and other usages. Other enumeration will be
changed to typedef's in the future.

955af4d4c1 maint: avoid 'const fooPtr' in virnet files
'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can).  But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).

1c02ed1421 util: utility functions for virNetDevVPortProfile
This patch adds three utility functions that operate on
virNetDevVPortProfile objects.

* virNetDevVPortProfileCheckComplete() - verifies that all attributes
    required for the type of the given virtport are specified.

* virNetDevVPortProfileCheckNoExtras() - verifies that there are no
    attributes specified which are inappropriate for the type of the
    given virtport.

* virNetDevVPortProfileMerge3() - merges 3 virtports into a single,
    newly allocated virtport. If any attributes are specified in
    more than one of the three sources, and do not exactly match,
    an error is logged and the function fails.

These new functions depend on new fields in the virNetDevVPortProfile
object that keep track of whether or not each attribute was
specified. Since the higher level parse function doesn't yet set those
fields, these functions are not actually usable yet (but that's okay,
because they also aren't yet used - all of that functionality comes in
a later patch.)

Note that these three functions return 0 on success and -1 on
failure. This may seem odd for the first two Check functions, since
they could also easily return true/false, but since they actually log
an error when the requested condition isn't met (and should result in
a failure of the calling function), I thought 0/-1 was more
appropriate.

21ea73e8f4 util: eliminate union in virNetDevVPortProfile
virNetDevVPortProfile has (had) a type field that can be set to one of
several values, and a union of several structs, one for each
type. When a domain's interface object is of type "network", the
domain config may not know beforehand which type of virtualport is
going to be provided in the actual device handed down from the network
driver at runtime, but may want to set some values in the virtualport
that may or may not be used, depending on the type. To support this
usage, this patch replaces the union of structs with toplevel fields
in the struct, making it possible for all of the fields to be set at
the same time.

This patch removes the explicit FSF address, and uses above instead

387117ad92 Convert 'raw MAC address' usages to use virMacAddr
Introduce new members in the virMacAddr 'class'
- virMacAddrSet: set virMacAddr from a virMacAddr
- virMacAddrSetRaw: setting virMacAddr from raw 6 byte MAC address buffer
- virMacAddrGetRaw: writing virMacAddr into raw 6 byte MAC address buffer
- virMacAddrCmp: comparing two virMacAddr
- virMacAddrCmpRaw: comparing a virMacAddr with a raw 6 byte MAC address buffer

then replace raw MAC addresses by replacing

- 'unsigned char *' with virMacAddrPtr
- 'unsigned char ... [VIR_MAC_BUFLEN]' with virMacAddr

and introduce usage of above functions where necessary.

15bbfd8390 util: Changes to support portprofiles for hostdevs
This patch includes the following changes to virnetdevmacvlan.c and
virnetdevvportprofile.c:

 - removes some netlink functions which are now available in
   virnetdev.c

 - Adds a vf argument to all port profile functions.

For 802.1Qbh devices, the port profile calls can use a vf argument if
passed by the caller. If the vf argument is -1 it will try to derive the vf
if the device passed is a virtual function.

For 802.1Qbg devices, This patch introduces a null check for the device
argument because during port profile assignment on a hostdev, this argument
can be null.

df81004632 network: support Open vSwitch
This patch allows libvirt to add interfaces to already
existing Open vSwitch bridges. The following syntax in
domain XML file can be used:

    <interface type='bridge'>
      <mac address='52:54:00:d0:3f:f2'/>
      <source bridge='ovsbr'/>
      <virtualport type='openvswitch'>
        <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
      </virtualport>
      <address type='pci' domain='0x0000' bus='0x00'
                          slot='0x03' function='0x0'/>
    </interface>

or if libvirt should auto-generate the interfaceid use
following syntax:

    <interface type='bridge'>
      <mac address='52:54:00:d0:3f:f2'/>
      <source bridge='ovsbr'/>
      <virtualport type='openvswitch'>
      </virtualport>
      <address type='pci' domain='0x0000' bus='0x00'
                          slot='0x03' function='0x0'/>
    </interface>

It is also possible to pass an optional profileid. To do that
use following syntax:

   <interface type='bridge'>
     <source bridge='ovsbr'/>
     <mac address='00:55:1a:65:a2:8d'/>
     <virtualport type='openvswitch'>
       <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'
                   profileid='test-profile'/>
     </virtualport>
   </interface>

To create Open vSwitch bridge install Open vSwitch and
run the following command:

    ovs-vsctl add-br ovsbr
