2.1.95 networking hassles

It's 4:26 am, so please bare with me.. it's been a long night...

I encountered a few problems with 2.1.95.

1) Network aliases seem to be completely broken. For instance:

ifconfig eth0:0 1.2.3.4 netmask 255.255.255.255 -broadcast
route add 1.2.3.4 eth0:0
or
route add -host 1.2.3.4 dev eth0:0

will create an eth0:0, however. the kernel routing tables show that it's
routed to eth0, not eth0:0. This completely screws up gated :)

2) Transparent port redirection is fubared:

# ipfwadm -I -a acc -P tcp -S 0/0 -D 0/0 80 -r 3128
# telnet localhost 80
[never ending scrolling oops here]

Machine had to be rebooted as the oops was... well never ending. Network
just stopped working.

3) Network routing entries are getting added more than once.

# route add -net 1.2.3.0
# route -n
1.2.3.0 0.0.0.0 255.255.255.0 UG 0 0 0 eth0
1.2.3.0 0.0.0.0 255.255.255.0 UG 0 0 0 eth0
1.2.3.0 0.0.0.0 255.255.255.0 UG 0 0 0 eth0

This is all done with net-tools 4.321 which the Changes file requires. The
"advanced router" part of the kernel wasn't turned on either.
