Re: [dpdk-users] Skeleton basicfwd sample app hits error [net_mlx5: DV flow is not supported] on Mellanox VF in VM

[Raslan Darawsheh <rasland@nvidia.com>]

Hello Das,

Can you kindly try to add the following devarg to your pci-whitelist ?
--pci-whitelist 0000:00:0d.0,dv_flow_en=0  -- pci-whitelist 0000:00:0e.0,dv_flow_en=0


Kindest regards,
Raslan Darawsheh
