hi hackers!

i just updated to 4.5-S and my gif0 tunnel stopped working. the reason
is the following:
o before (= 4.4-S) i used
  route add -inet6 default -interface gif0
o now (= 4.5-S) i need to do
  route add -inet6 default <ipv6-ptp-peer-addr>

when using the old setting, the system won't notice incoming packets,
i.e. there will be a SYN-ACK but no reply; the ACK is being ignored;
system continues to send SYNs.

i believe this behavior is not desired: man route explicitely allows
using the iface name if it is a point to point interface.

is this a bug or some special feature?
if bug i'm gonna file a pr when i got time to do so.

cheerz
