Subject: [PATCH v1] app/testpmd: set srv6 header without any TLV
Date: Tue, 28 Mar 2023 12:36:32 +0300	[thread overview]
Message-ID: <20230328093633.619965-1-rongweil@nvidia.com> (raw)

When the type field of the IPv6 routing extension is 4, it means
segment routing header.

In this case, set the last_entry to be segment_left minus 1 if the
user doesn't specify the header length explicitly.
