Add dpdk per-interface startup config parameter to support rss-flag
New parameter allows specifying rss-flag - one or more of following ipv4-frag ipv4-tcp ipv4-udp ipv4-sctp ipv4-other ipv4 ipv6-tcp-ex ipv6-udp-ex ipv6-frag ipv6-tcp ipv6-udp ipv6-sctp ipv6-other l2-payload ipv6-ex ipv6 Sample config: dpdk { dev 0000:86:00.0 { rss { ipv4 ipv4-tcp ipv4-udp } } } Change-Id: I33c047d69ef8710b8ba3c7e1a1964d5d54f6e880 Signed-off-by: Srivatsa Sangli <srivrama@cisco.com>
