Where I can see IFF_RENAMING interface flag ?

/usr/include/net/if.h

#define IFF_MONITOR     0x40000         /* (n) user-requested monitor 
mode */
#define IFF_STATICARP   0x80000         /* (n) static ARP */
#define IFF_DYING       0x200000        /* (n) interface is winding down */
#define IFF_RENAMING    0x400000        /* (n) interface is being renamed */
