---Problem Description---
When trying to bring up an ethernet port on a Shiner Network adapter, the
terminal outputs the following:
root@podkvm:~# ifconfig eth7 up

---Additional Hardware Info---
System firmware: 1427A
Machine Type = 8247-22L
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,
