Title:
  Install problem of Ubuntu on a z/VM Guest which has more than one
  NICDEF stmt

Status in debian-installer package in Ubuntu:
  Incomplete

Bug description:
  When trying to install Ubuntu distro on one of the IBM z/VM Guests
  which has more than one NICDEF statement defined in the user directory
  (Connected to more than one Vswitch at once) the installation process
  will add the network interface based on the ascending order of the NIC
  and not based on the param file

  - Machine Type = z/vM level 6.3 LPAR Z12 
  - Debugger       = A debugger is not configured
   
  ---Steps to Reproduce---
   
  System Information:
  z/VM level 6.3 or 6.4
  VSWITCH1 (VS1)  - NIC 700 ( 9dot)
  VSWITCH2 (VS2)  - NIC 900 (172dot)

  
  Recreate Steps:
  ---------------------
  1.  Create a new z/VM guests with connections to 2 different VSWITCHEs - VS1 and VS2 (nic 700 and 900 respectively)
  2. Start Installation via IBM Wave product and choose IP to be from VS2.
  The param file will be created as bellow:

  IGUB1610.INSTBASE:
  ro locale=C
  s390-netdevice/choose_networktype=qeth s390-netdevice/qeth/layer2=true s390-netd
  evice/qeth/port=0 s390-netdevice/qeth/choose=0.0.0900,0.0.0901,0.0.0902 netcfg/c
  onfirm_static=true netcfg/get_ipaddress=xxx.x.xxx.131 netcfg/get_hostname=  netc
  fg/hostname="IGUB1610" netcfg/get_domain=  netcfg/disable_dhcp=true netcfg/get_g
  ateway=xxx.x.xxx.254 netcfg/get_netmask=255.255.224.0 netcfg/disable_autoconfig=
  true netcfg/use_autoconfig=false netcfg/get_nameservers=127.0.0.1 disk-detect/mu
  ltipath/enable=true network-console/password=password network-console/password-a
  gain=password mirror/protocol=ftp mirror/ftp/hostname=davidre:<RepoPassword>@xxx
  .x.xxx.5 mirror/ftp/directory=//nfs/repo/Ubuntu16.10/

  3. Open z/VM guest and follow the installation process until the SSH
  session will be opened

  Actual Result:

  The SSH session is not opened and the IP remains unpingable since the
  Network interface that is added to the Guest at the installation
  beginning is etc700 instead etc900 that we expect for Vswitch 172dot

  Checked for other vswitches and it is always the same story - the
  network interface is added based on the ascending order of the
  available nics. In case Guest connected to 3 different vswitchs with
  NICs 300, 700, 900 and installation started for NIC 900, anyway  the
  network in the installation will be 300

  Output from 3270 guest's console:

  Kernel command line: ro locale=C                                 
                                      s390-netdevice/choose_networktype=qeth s390-
  netdevice/qeth/layer2=true s390-netdevice/qeth/port=0 s390-netdevice/qeth/choose
  =0.0.0900,0.0.0901,0.0.0902 netcfg/confirm_static=true netcfg/get_ipaddress=xxx.x.xxx.131 netcfg/get_hostname=  netcfg/hostname="IGUB1610" netcfg/get_domain=  n
  etcfg/disable_dhcp=true netcfg/get_gateway=xxx.x.xxx.254 netcfg/get_netmask=255.
  255.224.0 netcfg/disable_autoconfig=true netcfg/use_autoconfig=false netcfg/get_
  nameservers=127.0.0.1 disk-detect/multipath/enable=true network-console/password
                             
                                                Detecting link on enc700; please wait... 
  Expected:

  The network interface should be added based on the one provided in the
  param file


  Impact: Not possible to install Ubuntu on Guest that have more than
  one vswitch and the Vswitch for which we want installation to be done
  is not the first in the order (NICs order)
