The one big missing feature in s390-virtio was hotplugging. This is no more.
This patch implements hotplug add support, so you can on the fly add new devices
in the guest.
Keep in mind that this needs a patch for qemu to actually leverage the
functionality.

Many x86 instructions come in pairs - byte and word variants where bit 0
of the opcode determines operand size. Use this to simplify the decode
tables.

I suppose parse_pci_devfn() in qdev-properties should check the error.

This test use ping to check the virtual nics, it contains two kinds of test:
1. Packet loss ratio test, ping the guest with different size of packets.
