Some callers instantiate the device unconditionally, others will do so only
if there is a NICInfo to go with it. This appears to be fairly random, but
preseve the existing behaviour for now.

The first sunhme NIC gets placed a function 1 on slot 1 of PCI bus A,
and the rest are dynamically assigned on PCI bus B.

Previously, the first PCI NIC would be assigned to slot 2 even if the

Previously, the first PCI NIC would be placed in PCI slot 3 and the rest
would be dynamically assigned. Even if the user overrode the default NIC

Now, the first PCNet NIC (that is, anything not explicitly specified

The Malta board setup code would previously place the first NIC into PCI

The previous behaviour was: *if* the first NIC specified on the command
line was an RTL8139 (or unspecified model) then it gets assigned to PCI
slot 7, which is where the Fuloong board had an RTL8139. All other
devices (including the first, if it was specified as anything other than
an rtl8319) get dynamically assigned on the bus.
The new behaviour is subtly different: If the first NIC was given a
specific model *other* than rtl8139, and a subsequent NIC was not,
then the rtl8139 (or unspecified) NIC will go to slot 7 and the rest
will be dynamically assigned.

When instantiating XenBus itself, for each NIC which is configured with
either the model unspecified, or set to to "xen" or "xen-net-device",
create a corresponding xen-net-device for it.
Now we can revert the previous more hackish version which relied on the
platform code explicitly registering the NICs on its own XenBus, having
returned the BusState* from xen_bus_init() itself.
This also fixes the setup for Xen PV guests, which was previously broken
in various ways and never actually managed to peer with the netdev.

Most code which directly accesses nd_table[] and nb_nics uses them for
one of two things. Either "I have created a NIC device and I'd like a
configuration for it", or "I will create a NIC device *if* there is a
configuration for it". With some variants on the theme around whether
they actually *check* if the model specified in the configuration is
the right one.
Provide functions which perform both of those, allowing platforms to
be a little more consistent and as a step towards making nd_table[]
and nb_nics private to the net code.
One might argue that platforms ought to be consistent about whether
they create the unconfigured devices or not, but making significant
user-visible changes is explicitly *not* the intent right now.
The new functions leave the 'model' field of the NICInfo as NULL after
using it for the default NIC model, unlike the qemu_check_nic_model()
function which does set nd->model to match default_model explicitly.
This is acceptable because there is no code which consumes nd->model
except this NIC-matching code in net/net.c, and no reasonable excuse
for any code wanting to use nd->model in future.
Also export the qemu_find_nic_info() helper, as some platforms have
special cases they need to handle.

- Implementation of Receive function for packets
- Implementation for reading and writing from and to descriptors in
memory for Rx
When RX starts, we need to flush the queued packets so that they
can be received by the GMAC device. Without this it won't work
with TAP NIC device.
When RX descriptor list is full, it returns a DMA_STATUS for
software to handle it. But there's no way to indicate the software has
handled all RX descriptors and the whole pipeline stalls.
We do something similar to NPCM7XX EMC to handle this case.
1. Return packet size when RX descriptor is full, effectively dropping
these packets in such a case.
2. When software clears RX descriptor full bit, continue receiving
further packets by flushing QEMU packet queue.

The latest version of qemu (v8.2.0-869-g7a1dc45af5) crashes when booting
the mcimx7d-sabre emulation with Linux v5.11 and later.
qemu-system-arm: ../system/memory.c:2750: memory_region_set_alias_offset: Assertion `mr->alias' failed.
Problem is that the Designware PCIe emulation accepts the full value range
for the iATU Viewport Register. However, both hardware and emulation only
support four inbound and four outbound viewports.
The Linux kernel determines the number of supported viewports by writing
0xff into the viewport register and reading the value back. The expected
value when reading the register is the highest supported viewport index.
Match that code by masking the supported viewport value range when the
register is written. With this change, the Linux kernel reports
imx6q-pcie 33800000.pcie: iATU: unroll F, 4 ob, 4 ib, align 0K, limit 4G
as expected and supported.
