Title:
  Deploying node with di on armhf/keystone can't find BOOTIF

Status in MAAS:
  Incomplete
Status in “netcfg” package in Ubuntu:
  Fix Released
Status in “netcfg” source package in Trusty:
  Fix Committed

Bug description:
  [Impact]
  The interface=auto preseed option doesn't work on (some?) u-boot based systems, making d-i and MAAS fail in configurations where multiple external network interfaces are present.

  [Test Case]
  1) Get a u-boot-based system with multiple NICs attached.
  2) pxe boot d-i from the second NIC, passing "IPAPPEND 2" in the pxelinux config file
  3) Observe the warning "netcfg[$pid]: INFO: Could not find valid BOOTIF= entry in /proc/cmdline" in /var/log/syslog.

  When it is working, the installer should automatically try and
  configure whatever NIC was used to pxeboot, and the above error should
  not appear in syslog.

  [Regression Risk]
  The regression risk I see is that the new BOOTIF parsing code somehow regresses this feature on non-u-boot based systems.
