2021-01-21dpdk: do not use TSO for small packetsSomnath Kotur1-2/+5
Asking for TSO (TCP Segmentation Offload) on packets that are already smaller than (headers + MSS) does not make sense and may not work on some HW. Fix to only set the TSO flag when a segmentation offload is really required, i.e when packet is large enough.

2020-10-21dpdk: Disable VLAN filtering for VLAN sub-interface in i40e driverDimitrios Markou1-2/+2
When creating a VLAN sub-interface on a Fortville i40e DPDK VF, the data plane does not work properly. Enabling vlan filter offload overrides the VLAN strip offload setting to on. The VLAN strip offload must be disabled for VPP VLAN sub-interfaces to work.

2020-09-09interface: support configuring RSS steering queuesChenmin Sun1-0/+104
This patch adds the RSS steering queues set interface, and it's implementation in DPDK device: /* Interface to set rss queues of the interface */ typedef clib_error_t *(vnet_interface_rss_queues_set_t) (struct vnet_main_t * vnm, struct vnet_hw_interface_t * hi, clib_bitmap_t *bitmap); This patch also introduces a command line to set the RSS queues: set interface rss queues <interface> <list <queue-list>> To display the rss queues, use "show hardware-interfaces" Below is the example to configure rss queues for interface Gig0: vpp# set interface rss queues Gig0 list 0,2,4-7 vpp# show hardware-interfaces brief Name Idx Link Hardware VirtualFunctionEthernet18/1/0 1 down VirtualFunctionEthernet18/1/0 Link speed: unknown RSS queues: 0 2 4 5 6 7 local0 0 down local0 Link speed: unknown vpp# Users can also configure the rss queues on a dpdk interface in startup.conf: dpdk { dev 0000:18:01.0 { rss-queues 0,2,5-7 } } Type: feature Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: I1835595a1c54016a84eabee9fd62ce137935385d

2019-09-11dpdk: apply dual loop unrolling in DPDK TXLijian.Zhang1-0/+57
Too many prefetches within loop unrollings induce bottleneck and performance degradation on some CPUs which have less cache line fill buffers, e.g, Arm Cortex-A72. Apply dual loop unrolling and tune prefetches manually to remove hot-spot with prefetch instructions, to get throughput improvement. It brings about 1% throughput improvement and saves 8% clocks with the target node on Cortex-A72.

2018-05-31dpdk: Decoupling the meaning of xd->device_index in dpdk_pluginRui Cai1-10/+10
Prior to the change, dpdk plugin assumes xd->device_index is used both as index for internal dpdk_main->devices array and DPDK port index to call into DPDK APIs. However, when running on top of Failsafe PMDs, DPDK port index range may no longer be contiguous (as noted: http://dpdk.org/ml/archives/dev/2018-March/092375.html for related changes in DPDK). Because this, dpdk plugin can no longer iterate through all available DPDK ports with a for 0->rte_eth_dev_count() loop and the assumption of device_index no longer holds. This is part of initial effort to enable vpp running over dpdk on failsafe PMD in Microsoft Azure(3/4).
