Subject: error message: VF is not privileged to issue opcode 89-1

Hi experts,

I encounter the following error when creating SR-IOV VF for Emulex 10GB
nic on 3.8.13 kernel.

# modprobe be2net num_vfs=4

...

But the module gets loaded and VFs are created.
Also when the module is unloaded, below errors are seen in syslog:
  be2net 0000:30:04.0: VF is not privileged to issue opcode 89-1

I checked the code, this error occurs in be_probe() and the error opcode
89 is OPCODE_COMMON_SET_INTERRUPT_ENABLE, which is essential for an
initializing process IMO. And I also found this thread
https://lkml.org/lkml/2013/5/14/690, which shows there is a bug that VFs
will be probed before PFs. According to this thread, I guess I may
encountered the same error.
Anyone can confirm if this is a real error like I guess? Thanks.
