Hi Hanumanth, I agree with Thomas for the patch. 'eth_rx_metadata_negotiate_mp()' requests all Rx metadata offloads to be enabled, but at this stage if there is no flow rule for Rx metadata why it is consuming extra cycles? Can you update driver code to process Rx metadata when it is enabled by application (via 'rte_eth_rx_metadata_negotiate()') AND there is at least one flow rule for it?
