[Intel-wired-lan] How to enable trust for VF managed by the vfio-pci driver

[lgy]

Hi,


I'd like to enable promiscuous mode for a VF and the solution I found
online is to make it trust, so I first created the VF using i40e driver
(version: 1.5.16) and use the command *ip link set eth8 vf 0 trust on* to
configure it. Then I bind this VF to vfio-pci so it can be used by DPDK
application, but the promiscuous mode is not working. My guess is when I
unbind it from i40evf and bind to vfio-pci, the trust configuration has
been reset to off, so I'm wondering how to enable promiscuous mode for a VF
not managed by i40e driver?

Thanks,
Grace
