d1f6af6 "kvm-irqchip: simplify kvm_irqchip_add_msi_route" was a cleanup
of kvmchip routing configuration, that was mostly intended for x86.
However, it also contains a subtle change in behaviour which breaks EEH[1]
error recovery on certain VFIO passthrough devices on spapr guests. So far
it's only been seen on a BCM5719 NIC on a POWER8 server, but there may be
other hardware with the same problem. It's also possible there could be
circumstances where it causes a bug on x86 as well, though I don't know of
any obvious candidates.
Prior to d1f6af6, both vfio_msix_vector_do_use() and
vfio_add_kvm_msi_virq() used msg == NULL as a special flag to mark this
as the "dummy" vector used to make the host hardware state sync with the
guest expected hardware state in terms of MSI configuration.
Specifically that flag caused vfio_add_kvm_msi_virq() to become a no-op,
meaning the dummy irq would always be delivered via qemu. d1f6af6 changed
vfio_add_kvm_msi_virq() so it takes a vector number instead of the msg
parameter, and determines the correct message itself. The test for !msg
was removed, and not replaced with anything there or in the caller.
With an spapr guest which has a VFIO device, if an EEH error occurs on the
host hardware, then the device will be isolated then reset. This is a
combination of host and guest action, mediated by some EEH related
hypercalls. I haven't fully traced the mechanics, but somehow installing
the kvm irqchip route for the dummy irq on the BCM5719 means that after EEH
reset and recovery, at least some irqs are no longer delivered to the
guest.
In particular, the guest never gets the link up event, and so the NIC is
effectively dead.
[1] EEH (Enhanced Error Handling) is an IBM POWER server specific PCI-*
error reporting and recovery mechanism. The concept is somewhat
similar to PCI-E AER, but the details are different.

Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
Currently, devices are plugged before features are negotiated.
If the backend doesn't support VIRTIO_F_VERSION_1, the transport
needs to rewind some settings.
This is the case for CCW, for which a post_plugged callback had
been introduced, where max_rev field is just updated if
VIRTIO_F_VERSION_1 is not supported by the backend.
For PCI, implementing post_plugged would be much more
complicated, so it needs to know whether the backend supports
VIRTIO_F_VERSION_1 at plug time.
Currently, nothing is done for PCI. Modern capabilities get
exposed to the guest even if VIRTIO_F_VERSION_1 is not supported
by the backend, which confuses the guest.
This patch replaces existing post_plugged solution with an
approach that fits with both transports.
Features negotiation is performed before ->device_plugged() call.
A pre_plugged callback is introduced so that the transports can
set their supported features.
