>Description:
if there are one 128bit length host route exist and we add two network route 
which will conver the host route; then the kernel will print the log:Non-unique 
normal route, mask not entered
>How-To-Repeat:
enable radix mpath on the system(define RADIX_MPATH)
enable radix debug               (define RN6_DEBUG)
the tow macro will affect radix.c on the system

add the host route
ipv6 route 2192:168:5::1/128 VLAN 1 FE80::2D0:F8FF:FE22:33AB 

add the network route
ipv6 route 2192:168:5::0/48 VLAN 1 FE80::2D0:F8FF:FE22:33AB 
ipv6 route 2192:168:5::0/48 VLAN 2 FE80::2D0:F8FF:FE22:33AB 
then the kernel print the message : Non-unique normal route, mask not entered. 

the message is from the radix.c
