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 <chenmin.sun@intel.com> Change-Id: I213efc76dc8af37f2f63605884f353e05b0f5d2a
