Subject: [dpdk-dev] DEV_RX_OFFLOAD_SCATTER for ixgbe and igb devices
Date: Fri, 13 Apr 2018 14:52:22 +0000	[thread overview]
Message-ID: <CD7C01071941AC429549C17338DB8A5289214FDC@IRSMSX101.ger.corp.intel.com> (raw)

Hi all,

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.

https://mail.openvswitch.org/pipermail/ovs-dev/2018-April/345901.html

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?

Thanks
Ian
