Subject: [RFC 1/9] ethdev: add IPv6 routing extension header definition
Date: Wed, 21 Dec 2022 10:42:56 +0200 [thread overview]
Message-ID: <20221221084304.3680690-2-rongweil@nvidia.com> (raw)
In-Reply-To: <20221221084304.3680690-1-rongweil@nvidia.com>
Add IPv6 routing extension header definition and no
TLV support for now.
At rte_flow layer, there are new items defined for matching
type/nexthdr/segment_left field.
