Yes, this is exactly why I need to patch ixgbe PF. Otherwise it always
returns 1, even the number is configured as 4.
I will make some more experiments before sending the patch for review
in one or two days.

Hi Thomas,
Thanks for reply.
The kernel has older version of PF than the one released on sf.net. So
I'm checking the sf.net release.
If the change is limited in DPDK then it is controllable. But now it
affects Intel's PF driver, I don't even know how to push the feature
to Intel. The driver on sf
Hi,
I am doing experiments with SR-IOV + passthrough on 82599.
My expectation is to have VT on and DCB off, under which
configuration, the total 128 TX queues will be split into 32 pools,
each has 4 queues.
With latest driver ixgbe-3.18.7, PF can be set with 16 pools, each has
4 queues with these
