This function is used to manage a PCI BAR, so make the more generic
pci_register_io_region() available to other uses.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

VLANClientState's fd_read() handler doesn't read from file
descriptors, it adds a buffer to the client's receive queue.
Re-name the handlers to make things a little less confusing.

This, apparently, is the style we prefer - all VLANClientState
should be an argument to qemu_new_vlan_client().

We have both IRQ sinks and GPIO inputs. These are in principle exactly
the same thing, so remove the former.

The pci_register_device() call in PCI nic initialization routines can
fail. Handle this failure and propagate a meaningful error message to
the user instead of generating a SEGV.

rdra and tdra are already kept converted in the pcnet state structure.
Avoid converting derivatives a second time. The same case with the local
variable xmit_cxda: it already contains a converted cxda address. This
issue only causes troubles when using the pcnet in 16-bit legacy mode.

Change the PCI network drivers init functions to return the PCIDev, to

Also record PCIDevice structure on NICInfo to locate for release on
hot-removal.

This patch adds and uses #defines for PCI device classes and subclases,
using a new pci_config_set_class() function, similar to the recently
added pci_config_set_vendor_id() and pci_config_set_device_id().

This patch defines PCI vendor and device IDs in pci.h (matching those
from Linux's pci_ids.h), and uses those definitions where appropriate.
Change from v1:
Introduces pci_config_set_vendor_id() / pci_config_set_device_id()
accessors as suggested by Anthony Liguori.

I noticed that pcnet_common_init() takes an unused 'info_str'
parameter, added in r2142. Since then, we always pass "pcnet"
to register_savevm() (and never "lance").
Note that r6218 changed vc->info_str to "lance" for sun4m emulation.
On the assumption that it's not needed, this patch removes the
parameter. If reverting the change in r2142, and registering with
"lance" would be preferable, I can submit a patch to do so.

Some NIC init functions are only called when that model is
the only valid model. In that case, it makes sense to use
qemu_check_nic_model() from the NIC init function itself.

Allow the user to supply a vlan client name on the command line.
This is probably only useful for management tools so that they can
use their own names rather than parsing the output of 'info network'.

Don't lose track of what type/model a vlan client is so that we can
e.g. assign a global per-model id to clients.
The entire patch is basically a tedious excercise in making sure the
type/model string gets propagated down to qemu_new_vlan_client().

This patch enhances the pcnet NIC emulation with better loopback mode
support, including CRC generation for looped-back packets in "raw" mode.
The patch has practically no impact on the normal RX and TX path.
Successfully tested against an ancient proprietary pcnet driver that
does a lot of hardware checks on boot-up and now works fine over qemu as
well.
