[zebra] For solaris IPv6 PtP interfaces, try to support prefixlen != 128

2006-12-13 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* if_ioctl_solaris.c: (if_get_addr) For IPv6, stop assuming
	  that all IFF_POINTOPOINT have prefixlen of IPV6_MAX_BITLEN.
	  Instead, always try the SIOCGLIFSUBNET ioctl; if that fails,
	  then we fall back to IPV6_MAX_BITLEN for PtP interfaces.
