OK, that's what I suspected. Your config is missing the SR-IOV
capability structure. It would look something like this:
Capabilities: [160] Single Root I/O Virtualization (SR-IOV)
IOVCap: Migration-, Interrupt Message Number: 000
IOVCtl: Enable- Migration- Interrupt- MSE- ARIHierarchy-
IOVSta: Migration-
Initial VFs: 8, Total VFs: 8, Number of VFs: 0, Function Depende
ncy Link: 00
VF offset: 384, stride: 4, Device ID: 1520
Supported Page Size: 00000553, System Page Size: 00000001
VF Migration: offset: 00000000, BIR: 1
This is from a dump on an I350 controller on one of my lab systems.
This is a feature that is controlled by EEPROM settings. I'm guessing
that Dell has decided to defeature SR-IOV support for the I350 devices
on their daughter card. Or they could have made a mistake in
programming the EEPROM. In either case the attempt to enable SR-IOV on
devices without the SR-IOV capability structure will fail. I'd suggest
contacting your Dell supplier and getting further information from them.
