Currently it's the case that for some NICs (e.g. igb driver or ixgbe driver based), scatter_rx needs to be enabled explicitly in the case where it was not configured before.
A patch submitted for ovs-dpdk proposes to check that the DEV_RX_OFFLOAD_SCATTER flag is present in rte_ethdev_info.rx_offload_capa before setting scatter_rx.
While testing igb and ixgbe devices I spotted the DEV_RX_OFFLOAD_SCATTER flag is not set in rx_offload_capa.
As these devices require scatter_rx, should the scatter_rx flag be set for them as part of the eth_igb_infos_get() for igb and ixgbe_dev_info_get for ixgbe?
