Could I move
struct _virVirtualPortProfileDef {
enum virVirtualPortType virtPortType;
union {
struct {
uint8_t managerID;
uint32_t typeID; // 24 bit valid
uint8_t typeIDVersion;
unsigned char instanceID[VIR_UUID_BUFLEN];
} virtPort8021Qbg;
struct {
char profileID[LIBVIRT_IFLA_VF_PORT_PROFILE_MAX];
} virtPort8021Qbh;
} u;
};
into macvtap.h and still use it in the XML struct for the direct type
interface?
