Yet here we are... Most platforms iterating directly over the nd_table[] are doing one of two things. Either they are creating the NIC for their platform and want to find a matching -nic configuration for it, if such exists. Or they are only going to create that platform NIC if a matching config *does* exist. All of those can be converted to the new qemu_configure_nic_device() and qemu_create_nic_device() functions. The latter of which will call qdev_new() to create the device (and apply the config) if a matching NIC config does exist for it. The existing behaviour of each platform has been preserved for now, despite it being apparently fairly random. PCI and indeed XenBus can use a qemu_create_nic_bus_devices() which will create all NICs that live on a given bus type. That covers most platforms, but some PCI platforms do something special with the first NIC of a given type, placing it in the slot where it would have been on the real hardware. There were various inconsistencies in the way the platforms did so, and whether they cared what model the NIC was. Those subtle behavioural changes I *have* allowed to change, and now the pci_init_nic_slot() function will pick the first NIC that the user specified which isn't explicitly *not* the default type, and put that in the specified slot. The tests for npcm7xx used to lament that they had to instantiate both NICs even when they wanted to test only the second, because there was no way to specify which hardware devices gets which configuration. I made that untrue, by allowing 'emc0' and 'emc1' aliases, and fixed up the test accordingly. There are one or two special cases which want to do special things with the MAC address of the primary NIC, to set up a system identification (or force it to use an Apple OUI, in the case of m68k/q400). All those work out relatively cleanly too. And I can ditch the two ugly patches which fixed up the Xen network device handling, and replace them with a simple call to the new qemu_create_nic_bus_devices() function. I suspect that we can remove the pci_init_nic_devices() from platform code and just do it later, except for platforms which *care* which PCI bus the dynamic devices go on (is that just sun4u which puts its primary NIC onto a different bus?). Finally, while we're at it, clean up -nic model=help to only print the device models which are actually usable on the given platform rather than just listing them *all*. And now we can make nd_table[] and nb_nics static in net/net.c because nothing else has any business poking at them directly.
