The PR adds the s390x support. It sets the CCW devices and sets to false all the devices in the mapping isVirtioPCI. It reimplements the functions QemuNetdevParam and QemuDeviceParam to print an error message if the vhost-user devices are used. It introduces a new function ExecuteNetCCWDeviceAdd for qmp for the CCW devices. Fixes: #37 Co-authored-by: Yash D Jain <ydjainopensource@gmail.com> Signed-off-by: Alice Frosi <afrosi@de.ibm.com>
