Currently for both qemu-system-arm and qemu-system-aarch64
the default board model if the user doesn't specify one
is the 'integratorcp'. This is a totally arbitrary historical
accident since it was the first board to be modelled.
That board is now just one target among many for us, and
is a very poor choice of default:
* it's an ancient board that is now only found in the
junkpiles of longtime ARM/Linux hackers, if at all
* it's an ARMv5 CPU, when most distros are now assuming
ARMv7
* it's pretty much unmaintained in QEMU
* it doesn't even have versatilepb's advantage of
supporting PCI
Making it or any other board the default serves only
to confuse people new to ARM who expect something more
like the x86 monoculture. Remove the is_default marker
from integratorcp, and don't set it for any other board,
to give users a nudge that they need to think about
which board they want a QEMU model of. (QEMU will produce
the admittedly slightly cryptic error "No machine found.")

Stefan Fritsch just fixed a virtio-net driver bug [1], virtio-net won't
filter out VLAN-tagged packets if VIRTIO_NET_F_CTRL_VLAN isn't negotiated.
This patch added a new field to @RxFilterInfo to indicate vlan receive
state ('normal', 'none', 'all'). If VIRTIO_NET_F_CTRL_VLAN isn't
negotiated, vlan receive state will be 'all', then all VLAN-tagged packets
will be received by guest.
This patch also fixed a boundary issue in visiting vlan table.

acpi: make SSDT 1.0 spec compliant when possible
We are back to old encoding.
Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
The ACPI specification says:
The ASL compiler can emit two different AML opcodes for a Package
declaration, either PackageOp or VarPackageOp. For small, fixed-length
packages, the PackageOp is used and this opcode is compatible with ACPI
1.0. A VarPackageOp will be emitted if any of the following conditions
are true:
. The NumElements argument is a TermArg that can only be resolved at
runtime.
. At compile time, NumElements resolves to a constant that is larger than
255.
. The PackageList contains more than 255 initializer elements.
Note: The ability to create variable-sized packages was first introduced
in ACPI 2.0. ACPI 1.0 only allowed fixed-size packages with up to 255 elements.
So the spec seems to say a fixed value up to 255 must always
be used with PackageOp and not VarPackageOp, and some guests
(windows up to win2k8) seem to interpret it like this.
Let's do just this, choosing the encoding depending on
the number of elements.
Fixes 9bcc80cd71
(i386/acpi-build: allow more than 255 elements in CPON).
