Zusammenfassung:A method for updating a descriptor engine for a network interface card (NIT) can include quiescing, by a processing device, a transmit stream to the NIC. The method can further include stopping, by the processing device, a descriptor engine from providing new receive descriptors to the NIC. The method can further include setting, by the processing device, a controller to redirect inbound traffic to the memory. The method can further include restoring, by the processing device, a transmit configuration and a transmit state of the descriptor engine subsequent to updating the descriptor engine.
