ifconfig bug removes aliases

[Aron Griffis <aron@xxxxxx>]

Hello, here is the sequence:

    ifconfig eth0:1 10.10.10.1 netmask 255.255.0.0 
    ifconfig eth0:2 10.10.10.2 netmask 255.255.0.0 
    ifconfig eth0:1 down

At this point eth0:2 has disappeared also.  It appears that the aliases
must be on the same subnet for this to occur, and the creation order is
also important.
