> This patch adds priv-flag knob to configure global true promisc support. With
> this patch the user can decide the flavor of promiscuous that the VFs will see
> when promiscuous mode is enabled on the interface. Since this a global
> setting for the whole device, the priv-flag is exposed only on the first PF of
> the device.
> 
> The default is true promisc support is off, which means the promisc mode for
> the VF will be limited/defport mode.
> 
> For the PF, we still will be in limited promisc unless in MFP mode irrespective
> of the flavor picked through this knob.
> 
> Usage:
> On PF0
> ethtool --show-priv-flags p261p1
> Private flags for p261p1:
> MFP                    : off
> LinkPolling            : off
> flow-director-atr      : on
> veb-stats              : off
> hw-atr-eviction        : off
> vf-true-promisc-support: off
> 
> to enable setting true promisc
> ethtool --set-priv-flags p261p1 vf-true-promisc-support on
> 
> At this point if the VF is set to trust and promisc is enabled on the VF through
> ip link set ... promisc on The VF/VFs will be able to see ALL ingress traffic

VF promiscuous mode works as expected
