Hello Rusty, this is a small fix for virtio_net. virtnet_probe already calls alloc_etherdev, which calls ether_setup. There is no need to do that again.

This attempts to implement a "virtual I/O" layer which should allow common drivers to be efficiently used across most virtual I/O mechanisms. It will no-doubt need further enhancement. The details of probing the device are left to hypervisor-specific code: it simple constructs the "struct virtio_device" and hands it to the probe function (eg. virtnet_probe() or

Hi, These patches add support for S4 to virtio (pci) and all drivers. For each driver, all vqs are removed before hibernation, and then re-created after restore. Some driver-specific uninit and init work is also done in the freeze and restore functions. All the drivers in testing work fine: * virtio-blk is used for the only disk in the VM, IO works fine before and after. * virtio-console:
