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

[Mori, Naoyuki]

Hi Grace,

Have you set ?vf-true-promisc-support on? from PF?
See https://patchwork.ozlabs.org/patch/618187/

However, you may not see broadcast packet on VF if you haven?t assign VLAN ID to VF.
Hope this help.

Regards,
Mori

    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
