Subject: [PATCH v6 1/3] ethdev: add IPv6 routing extension header definition
Date: Thu, 2 Feb 2023 12:00:19 +0200 [thread overview]
Message-ID: <20230202100021.2445976-2-rongweil@nvidia.com> (raw)
In-Reply-To: <20230202100021.2445976-1-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/segments_left field.
Add command line support for IPv6 routing extension header
matching: type/nexthdr/segment_list.
