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
}
}
}
