Bug Description
Crash trace attached.
Once rps is done, the handler tries to extract vif from the control block. From that vif we try to get the dev and the rx_handler_data (which should be equal to the vif). From whatever information that was present in the trace, it was confirmed that rx_handler_data was null. There could be a case where agent restarts and is in the process of soft resetting the vrouter when this condition can happen. Since we do not have dump, for now we will provide a fix with the available information.
