Hi, this is Kunihiro.

I think I find the reason why this occur.  

zebra try to get interface's index by SIOCGIFINDEX when it's defined.
With glibc SIOCGIFINDEX is defined in /usr/include/ioctls.h but it
doesn't exist in /usr/include/linux/sockios.h.  So zebra try to get
interface's index by SIOCGIFINDEX but it isn't suppoted by the kernel.

So I've changed code if SIOCGIFINDEX is defined and return error
interface's index remain zero.

o When ioctl (SICGIFINDEX) returns error silently ignore it. And
  interface's index remain zero.
o Set address family when we get interface's address by SIOCGIFADDR.
o zebra : ip address filter coding is started.
