Summary

The patch is ported from
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ddae0349fdb78bcc5e7219061847012aa1a29069

This is OK, because the driver in Linux side is dual-licensed (GPL & BSD)

Without the patch, when trying to enable SR-IOV for the Mellanox
ConnectX-3 VF with Hyper-V, I get the below error:

mlx4_en: mlx4_core0: Port 1: failed reserving qp for TX ring
mlx4_en: mlx4_core0: Port 1: Failed to allocate NIC resources
