Hi, is there a specific reason that the rx offload capability DEV_RX_OFFLOAD_SCATTER is not available in the i40e and cxgbe drivers in DPDK 18.08? We previously used this feature with DPDK 17.11 to handle jumbo frames while using 2k mbufs and it worked without a problem. It also seems that simply adding the flag to dev_info->rx_offload_capa makes it work again. Best regards, Martin

Yes, DEV_RX_OFFLOAD_SCATTER seems to have been missed in Rx offload
caps for cxgbe. Will send a patch. Thanks for reporting.
