This patch, by QLogic, fixes the bug. It will set the card back to LE mode after it's booted from a BE kernel, that leaves it at BE mode.

  I can get the interface up on petitboot and on a 3.10 kernel used for PowerKVM installer. I can't do it for Ubuntu 14.04 kernel, based on 3.13. I can reproduce the same thing with a 3.13 kernel on another PowerNV system.

  However, it works on a PCI passthrough environment on PowerKVM, with
  both 14.04 kernel and 14.10. So, this is specific to PowerNV. I will
  try upstream kernel versions and see if it's possible to find a
  culprit.

  I collected this with msglevel options on the driver. The driver
  specific option SP, timer, interrupt, link, ifup, and probe.

  I couldn't find Thadeu's kernel. I built the newer kernel + bnx2x
  driver from upstream, still saw the same failure. I will look into
  more.

  Thanks,
