>Description:
ndp.8 says that, with temp option, we can insert an non-permanent NDP entry to the kernel.
However, it doesn't work. It seems that ndp correctly passes an expire value (> 0)
to the kernel, but the kernel ignores it.
>How-To-Repeat:
# ndp -s fc00::101 52:54:00:bb:18:01 temp
# ndp -n fc00::101
Neighbor                             Linklayer Address  Netif Expire    S Flags
fc00::101                            52:54:00:bb:18:01    wm0 permanent R 

The "Expire" column shouldn't be "permanent".
>Fix:
N/A

I guess this can probably be closed.  It works for me with -current
and looking back through changes probably since you revision 1.178
commit where you separated nexthop caches from the routing table.

After the commit lla_rt_output is receiving and setting expiry time.
