@Joshph, "the test kernel in #25" means the #4 in the link of #25,

It looks to me the patch is not included. Just want to confirm my guess.

Is the VF device not showing up only with my test kernel posted in

If the new issue only happens with my test kernel, can you test the

A quick test on the kernel in comment #14:
Mellanox CX3 VF device is not showing up when booting up with this test kernel:

Yes, it might be best to have a separate bug. That way we can track it

Mellanox has told me that the following three commits are needed for SR-IOV in
Azure:
1. d585df1c5ccf net/mlx4_core: Avoid command timeouts during VF driver
device shutdown
2. 7c3945bc2073 net/mlx4_core: Fix when to save some qp context flags for
dynamic VST to VGT transitions
3.
Mellanox assures us that all the ConnectX3 drivers are upstream now, so
I will switch focus on the kernel side to integrating those once I have
the commits. DPDK however has userspace which come from this repo:

Joshua - I looked at mlnx-ofed-kernel-
dkms_3.4-OFED.3.4.2.0.0.1.g30039f7_all.deb in some detail. It appears
that nearly all of the drivers contained therein are replacements for
existing drivers in the linux v4.4 kernel. Even without looking at the
code for these replacement drivers, I can say
Mellanox has pointed me to a repository that has the minimal set of
drivers and utilities needed for SR-IOV (and, eventually, DPDK).
Consider the "mlnx_rdma_minimal" repository, here:
http://linux.mellanox.com/public/repo/mlnx_rdma_minimal/
I am requesting the latest 64-bit drivers and userspace
I'll pester Mellanox on that. Thanks!
