Subject: [PATCH net-next] nfp: flower: support to offload pedit of IPv6 flowinto fields

From: Yinjun Zhang <yinjun.zhang@...igine.com>

Previously the traffic class field is ignored while firmware has
already supported to pedit flowinfo fields, including traffic
class and flow label, now add it back.
