dhclient deletes ifaddr, then fails

["Simon 'corecode' Schubert" <corecode@xxxxxxxxxxxx>]

Hey,

considering this sequence:

	dhclient fxp0

now we have ip address & everything is fine.  dhclient keeps running

	dhclient fxp0

returns error 1.  in syslog, it complains about the address already 
beeing taken, because of the running dhlient.  However, it will set the 
ip address of fxp0 to 0.0.0.0.  Now I'm left with an unusable system.

	killall dhclient
	dhclient fxp0

now it works again.

cheers
  simon
