how let intel 82599 controller dispatch(proxy) lldp packet to underlying VFs ? can it be achieved by modifying ixgbe driver code?

Our case is app inside KVM need LLDP packet from VF. So we'd like to know how to enable this. Can this be achieved by hack ixgbe driver code or just do some proper settings for the driver ?

Hello schen219,

 

Thank you for posting in Intel Ethernet Communities. 

 

Before we proceed, please confirm if you are using ixgbe driver and if yes, please provide the link where you downloaded the driver.

 

And also, are you using KVM Linux?

Hello schen219,

 

How were you able to turn on trust vf?

By the way, are you using an on-board NIC or a PCIe NIC?

 

If you still have questions, please let us know.
