I have finished my "home work".
issue reproduced with 4.0.0 kernel and latest 4.1.1 ixgbe driver.
Same error in dmesg:
[ 221.676388] ixgbe :00:05.0 :00:05.0 (uninitialized): Failed

Hello!
After some investigation of ixgbe and Linux kernel code.
I found function which return this "error 38", it's sriov_enable from
Linux Kernel
(http://lxr.free-electrons.com/source/drivers/pci/iov.c?v=3.16#L173).
And error 38 means return of ENOSYS

Sorry, for the mess. It was very hard day and I post fe silly posts
due to my inattention (and incorrectly selected ssh window).
Finally, I have got only single issue with ixgbe driver there.
I can't create VF inside KVM VM. Not with max_vfs param, not with echo

Hello!
Please ignre this:
echo 2 > /sys/devices/pci:00/:00:02.0/:03:00.0/sriov_numvfs
-bash: echo: write error: Function not implemented
echo 2 > /sys/devices/pci:00/:00:02.0/:03:00.1/sriov_numvfs
-bash: echo: write error: Function not implemented
Now it works fine. But
Hello!
Some details.

Definitely related with non existent proc fs path:
find /proc/|grep sriov_numvfs|wc -l

It's definitely a bug.
Because I could find th
