Did this work in a less recent -current?

I noted that I couldn't tcpdump on an interface with no address in 1.4V
and I suspect this is the same problem.  However I didn't exactly expect
it to work.

It does work this way though:

# ifconfig tlp0 inet 0.0.0.0 netmask 255.255.255.255
# ifconfig tlp0                                      
tlp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: Ethernet 10baseT
        status: active
        inet 0.0.0.0 netmask 0xffffffff 
        inet6 fe80::722f:53ff:fec0:f02e%tlp0 prefixlen 64 scopeid 0x2
# tcpdump -vvv -n -i tlp0
tcpdump: listening on tlp0
