Documentation/networking/operstates.txt (and netdevice(7)) claims that
the flags IFF_LOWER_UP, IFF_DORMANT and IFF_ECHO can be read from user space
using ioctl() with SIOCGIFFLAGS. Looking in include/linux/if.h however,
the flags are returned in a struct ifreq in the field ifr_flags which
is declared as a short, while the flags are defined as:

#define IFF_LOWER_UP    0x10000         /* driver signals L1 up         */
#define IFF_DORMANT     0x20000         /* driver signals dormant       */
#define IFF_ECHO        0x40000         /* echo sent packets            */
