Currently, MAC registration occurs during device creation, which is
early enough that, during live migration, you end up with duplicate
MAC addresses on still-running source and target devices, even though
the target device isn't actually being used yet.
This patch proposes to defer MAC registration until right before
the guest can actually use the device -- In other words, right
before starting guest CPUs.

Ethernet interfaces in libvirt currently do not support bandwidth setting.
For example, following xml file for an interface will not apply these
settings to corresponding qdiscs.
<interface type="ethernet">
<mac address="02:36:1d:18:2a:e4"/>
<model type="virtio"/>
<script path=""/>
<target dev="tap361d182a-e4"/>
<bandwidth>
<inbound average="984" peak="1024" burst="64"/>
<outbound average="2000" peak="2048" burst="128"/>
</bandwidth>
</interface>

Currently, there is one flag passed in during macvtap creation
(withTap) -- Let's convert this field to an unsigned int flag
field for future expansion.

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.

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.
This patch resolves https://bugzilla.redhat.com/show_bug.cgi?id=815270
The function virNetDevMacVLanVPortProfileRegisterCallback() takes an
arg "virtPortProfile", and was checking it for non-NULL before using
it. However, the prototype for
virNetDevMacVLanPortProfileRegisterCallback had marked that arg with
ATTRIBUTE_NONNULL(). Contrary to what one may think,
ATTRIBUTE_NONNULL() does not provide any guarantee that an arg marked
as such really is always non-null; the only effect to the code
generated by gcc, is that gcc *assumes* it is non-NULL; this results
in, for example, the check for a non-NULL value being optimized out.
(Unfortunately, this code removal only occurs when optimization is
enabled, and I am in the habit of doing local builds with optimization
off to ease debugging, so the bug didn't show up in my earlier local
testing).
In general, virPortProfile might always be NULL, so it shouldn't be
marked as ATTRIBUTE_NONNULL. One other function prototype made this
same error, so this patch fixes it as well.
This patch adds a netlink callback when migrating a VEPA enabled
virtual machine. It fixes a Bug where a VM would not request a port
association when it was cleared by lldpad.
This patch requires the latest git version of lldpad to work.

When libvirtd is restarted, also restart the netlink event
message callbacks for existing VEPA connections and send
a message to lldpad for these existing links, so it learns
the new libvirtd pid.

Update virNetDevMacVLanCreateWithVPortProfile to allow creation
of plain macvlan devices, as well as macvtap devices. The former
is useful for LXC containers
* src/qemu/qemu_command.c: Explicitly request a macvtap device
* src/util/virnetdevmacvlan.c, src/util/virnetdevmacvlan.h: Add
new flag to allow switching between macvlan and macvtap
creation
Move the low level macvlan creation APIs into the
virnetdevmacvlan.c file where they more naturally
belong
* util/interface.c, util/interface.h: Remove virNetDevMacVLanCreate
and virNetDevMacVLanDelete
* util/virnetdevmacvlan.c, util/virnetdevmacvlan.h: Add
virNetDevMacVLanCreate and virNetDevMacVLanDelete
Rename virNetDevMacVLanCreate to virNetDevMacVLanCreateWithVPortProfile
and virNetDevMacVLanDelete to virNetDevMacVLanDeleteWithVPortProfile
To make way for renaming the other macvlan creation APIs in
interface.c
* util/virnetdevmacvlan.c, util/virnetdevmacvlan.h,
qemu/qemu_command.c, qemu/qemu_hotplug.c, qemu/qemu_process.c:
Rename APIs
Rename the macvtap.c file to virnetdevmacvlan.c to reflect its
functionality. Move the port profile association code out into
virnetdevvportprofile.c. Make the APIs available unconditionally
to callers
* src/util/macvtap.h: rename to src/util/virnetdevmacvlan.h,
* src/util/macvtap.c: rename to src/util/virnetdevmacvlan.c
* src/util/virnetdevvportprofile.c, src/util/virnetdevvportprofile.h:
Pull in vport association code
* src/Makefile.am, src/conf/domain_conf.h, src/qemu/qemu_conf.c,
src/qemu/qemu_conf.h, src/qemu/qemu_driver.c: Update include
paths & remove conditional compilation
