Summary: [vt-d] dom0 igb driver is too old to support 4-port
Kawela
Product: Xen
Version: unstable
Platform: Other
OS/Version: Windows
Status: NEW
Severity: normal
Priority: P1
Component: Linux-pv_ops dom0

Bug detailed description:
--------------------------
For 4-port Kawela which has SR/IOV supported, the Virtual Functions can not be
enabled in default, but for 2-port Kawela on the same machine, the Virtual
Functions can be recognized.
We try to enable Virtual Functions manually.
# modprobe igb max_vfs=2
it complains "SR-IOV: bus number out of range", the VFs can not be enabled,
either.
And more, we already add dom0 parameter "iommu_inclusive_mapping=1" when we do
the testing.
Reproduce steps:
----------------
1. Install 4-port Kawela card on test machine
2. Run command "lspci" to check all the availabe BDFs, and confirm whether the
VFs were enabled.
3. If the VFs are not enabled, run command " modprobe igb max_vfs=2 " to enable
them manually.
Current result:

Expected result:
----------------
Basic root-causing log:
----------------------
the output of command "modprobe igb max_vfs=2"
