Re: [PATCHv2 net-next 1/3] net: Add provision to specify pf number while assigning VF mac

could control their > VFs. Hi Dave and all, Based on above comment, since the control node should always be net_device, we will go with the below implementation. We will have dummy net devices with 00:00:00:00:00:00 mac address. The device won't be associated with any port, since it doesn't need to transmit/receive. On a two port adapter, we need to create 4 dummy net devices, corresponding to PF0 ... PF3. Basically the dummy net device will have callback's only for "ndo_set_vf_*" API's. Thanks, Hariprasad Shenai
