From 24e2c50bf34af37b688df83cd8d39a58345349c5 Mon Sep 17 00:00:00 2001 From: Chenmin Sun Date: Fri, 28 Feb 2020 22:49:37 +0800 Subject: flow: add RSS support This patch enables the RSS configuration through vnet/flow interface With this RSS feature, users can config the RSS functions for specific flows Currently, it supports: default, toeplitz and symmetric_toeplitz rss function, and ipv4-tcp/ipv4-udp/ipv6-tcp/ipv6-ucp flow types Users can use the following options to combine with above flow types for more specific hash input set selection: l3-src-only, l3-dst-only, l4-src-only, l4-dst-only Command line: test flow add dst-ip any proto udp rss function default rss types ipv4-tcp use l3-dst-only test flow add dst-ip any proto udp rss function toeplitz rss types ipv4-udp use l4-src-only test flow add dst-ip any proto udp rss function symmetric_toeplitz rss types ipv6-udp use l3-src-only and l3-dst-only Type: feature Signed-off-by: Chenmin Sun Change-Id: I213efc76dc8af37f2f63605884f353e05b0f5d2a --- src/plugins/dpdk/device/dpdk.h | 27 +++++++++++++++++++ src/plugins/dpdk/device/flow.c | 56 +++++++++++++++++++++++++++++++++++----- src/plugins/dpdk/device/format.c | 26 ++----------------- src/plugins/dpdk/device/init.c | 3 ++- 4 files changed, 80 insertions(+), 32 deletions(-) (limited to 'src/plugins') diff --git a/src/plugins/dpdk/device/dpdk.h b/src/plugins/dpdk/device/dpdk.h index a0441818899..46d36a2b5aa 100644 --- a/src/plugins/dpdk/device/dpdk.h +++ b/src/plugins/dpdk/device/dpdk.h @@ -410,6 +410,33 @@ typedef enum void dpdk_update_link_state (dpdk_device_t * xd, f64 now);
