[dpdk-stable] [PATCH] net/i40e: fix IPv6 fragment RSS offload type in flow

[Alvin Zhang]

To keep flow format uniform with ice, this patch adds support for
this RSS rule:
    flow create 0 ingress pattern eth / ipv6_frag_ext / end actions \
    rss types ipv6-frag end queues end queues end / end

Fixes: ef4c16fd9148 ("net/i40e: refactor RSS flow")
