Cannot bring up 2nd NIC two times in a row on DHCP.

[Hanasaki JiJI <hanasaki@hanaden.com>]

I have the following in my interfaces file of a firewall.  eth0 is the 
external NIC and eth1 is the internal NIC.  I am getting DHCP addys from 
my provider.

The following list of commands hangs:

   * ifup eth0
   * ifup eth1
   * ifdown eth1 eth0
   * ifup eth1

The following works ok:

   * ifup eth0
   * ifup eth1
   * ifdown eth1 eth0
   * *rmmod tulip*
   * ifup eth1


# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
iface lo inet loopback
iface eth0 inet dhcp
iface eth1 inet static
       address 192.168.1.1
       netmask 255.255.255.0
       network 192.168.1.0
       broadcast 255.255.255.0
