private netdev flags into UAPI?

not sure if this has been brought up before, but I realized that the private IFF_yyy netdevice flags which weren't exposed to user space so far have been moved to include/uapi/linux/if.h, isn't that wrong?

Or.

/* Private (from user) interface flags (netdevice->priv_flags). */
#define IFF_802_1Q_VLAN 0x1             /* 802.1Q VLAN device.          */
#define IFF_EBRIDGE     0x2             /* Ethernet bridging device.    */
[...]                                  * change when it's running */
