The values returned by eth_get_protocols() are used to perform RSS,
checksumming and segmentation. Even when a packet signals the use of the
protocols which these operations can be applied to, the headers for them
may not be present because of too short packet or fragmentation, for
example. In such a case, the operations cannot be applied safely.
Report the presence of headers instead of whether the use of the
protocols are indicated with eth_get_protocols(). This also makes
corresponding changes to the callers of eth_get_protocols() to match
with its new signature and to remove redundant checks for fragmentation.

Currently, VMXNET3_MAX_MTU itself (being 9000) is not considered a
valid value for the MTU, but a guest running ESXi 7.0 might try to
set it and fail the assert [0].
In the Linux kernel, dev->max_mtu itself is a valid value for the MTU
and for the vmxnet3 driver it's 9000, so a guest running Linux will
also fail the assert when trying to set an MTU of 9000.
VMXNET3_MAX_MTU and s->mtu don't seem to be used in relation to buffer
allocations/accesses, so allowing the upper limit itself as a value
should be fine.

There were several different ways to deal with the situation where the
vector specified for a msix function is out of bound:
- early return a function and keep progresssing
- propagate the error to the caller
- mark msix unusable
- assert it is in bound
- just ignore
An out-of-bound vector should not be specified if the device
implementation is correct so let msix functions always assert that the
specified vector is in range.
An exceptional case is virtio-pci, which allows the guest to configure
vectors. For virtio-pci, it is more appropriate to introduce its own
checks because it is sometimes too late to check the vector range in
msix functions.

In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.
While there, delete a few superfluous inclusions of hw/qdev-core.h.
Touching hw/qdev-properties.h now recompiles some 1200 objects.

At some point vmxnet3 live migration stopped working and git-bisect
didn't help finding a working version.
The issue is the PCI configuration space is not being migrated
successfully and MSIX remains masked at destination.
Remove the migration differentiation between PCI and PCIe since
the logic resides now inside VMSTATE_PCI_DEVICE.
Remove also the VMXNET3_COMPAT_FLAG_DISABLE_PCIE based differentiation
since at 'realize' time is decided if the device is PCI or PCIe,
then the above macro is enough.
Use the opportunity to move to the standard VMSTATE_MSIX
instead of the deprecated SaveVMHandlers.

pvrdma setup requires vmxnet3 device on PCI function 0 and PVRDMA device
on PCI function 1.
pvrdma device needs to access vmxnet3 device object for several reasons:
1. Make sure PCI function 0 is vmxnet3.
2. To monitor vmxnet3 device state.
3. To configure node_guid accoring to vmxnet3 device's MAC address.
To be able to access vmxnet3 device the definition of VMXNET3State is
moved to a new header file.

The bus pointer in PCIDevice is basically redundant with QOM information.
It's always initialized to the qdev_get_parent_bus(), the only difference
is the type.
Therefore this patch eliminates the field, instead creating a pci_get_bus()
helper to do the type mangling to derive it conveniently from the QOM
Device object underneath.

Since commit ab06ec4357 we test the vmxnet3 device in the
pxe-tester, too (when running "make check SPEED=slow"). This now
revealed that the code is not working there if the host is a big
endian machine (for example ppc64 or s390x) - "make check SPEED=slow"
is now failing on such hosts.
The vmxnet3 code lacks endianness conversions in a couple of places.
Interestingly, the bitfields in the structs in vmxnet3.h already tried to
take care of the *bit* endianness of the C compilers - but the code missed
to change the *byte* endianness when reading or writing the corresponding
structs. So the bitfields are now wrapped into unions which allow to change
the byte endianness during runtime with the non-bitfield member of the union.
With these changes, "make check SPEED=slow" now properly works on big endian
hosts, too.

The checksum algorithm used by IPv4, TCP and UDP allows a zero value
to be represented by either 0x0000 and 0xFFFF. But per RFC 768, a zero
UDP checksum must be transmitted as 0xFFFF because 0x0000 is a special
value meaning no checksum.
Substitute 0xFFFF whenever a checksum is computed as zero when
modifying a UDP datagram header. Doing this on IPv4 and TCP checksums
is unnecessary but legal. Add a wrapper for net_checksum_finish() that
makes the substitution.
(We can't just change net_checksum_finish(), as that function is also
used by receivers to verify checksums, and in that case the expected
value is always 0x0000.)

The following devices support both PCI Express and Conventional
PCI, by including special code to handle the QEMU_PCI_CAP_EXPRESS
flag and/or conditional pcie_endpoint_cap_init() calls:
* vfio-pci (is_express=1, but legacy PCI handled by
vfio_populate_device())
* vmxnet3 (is_express=0, but PCIe handled by vmxnet3_realize())
* pvscsi (is_express=0, but PCIe handled by pvscsi_realize())
* virtio-pci (is_express=0, but PCIe handled by
virtio_pci_dc_realize(), and additional legacy PCI code at
virtio_pci_realize())
* base-xhci (is_express=1, but pcie_endpoint_cap_init() call
is conditional on pci_bus_is_express(dev->bus)
* Note that xhci does not clear QEMU_PCI_CAP_EXPRESS like the
other hybrid devices

Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.
Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.
Note: If you add an error exit in your pre_save you must emit
an error_report to say why.
