Subject3.11-rc4 ixgbevf: endless "Last Request of type 00 to PF Nacked" messages
When I enable VFs via sysfs on an Intel X540-AT, I see an endless stream of

ixgbevf 0000:08:10.2: Last Request of type 03 to PF Nacked

messages. This on an HP z420 with the Intel X540-AT in external Magma
PCIe expansion chassis. No cable is attached to the X540-AT.

ixgbe is built as a module and is auto-loaded during boot, with no VFs
enabled. The "Last request Nacked" messages start when I enable VFs
with:

# echo -n 8 > /sys/bus/pci/devices/0000:08:00.0/sriov_numvfs
ixgbe 0000:08:00.0 eth1: SR-IOV enabled with 8 VFs
pci 0000:08:10.0: [8086:1515] type 00 class 0x020000
pci 0000:08:10.2: [8086:1515] type 00 class 0x020000
...
ixgbevf: Intel(R) 10 Gigabit PCI Express Virtual Function Network
Driver - version 2.7.12-k
...
ixgbevf 0000:08:10.2: Last Request of type 03 to PF Nacked
...

This happens with v3.11-rc4, v3.10, and v3.9, which is as far back as
I checked. Complete console log and lspci output are here:
