XDP doesn't cooperate with the bridge code, and it works on a layer before the bridge. For the ixgbe driver it does a full link down/up (to reconfigure all the NIC queues), which is why you likely you see this 5 sec issue, as you have enabled STP on your bridge. (Note, replacing an XDP-prog with another XDP-prog does not require this link down/up). -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
