Subject: [PATCH v2 2/2] app/testpmd: fix SW L4 checksum in multi-segments
Date: Wed, 29 Dec 2021 09:37:02 +0000 [thread overview]
Message-ID: <20211229093702.1930214-3-kevinx.liu@intel.com> (raw)
In-Reply-To: <20211229093702.1930214-1-kevinx.liu@intel.com>
Testpmd forwards packets in checksum mode that it needs to calculate
the checksum of each layer's protocol.
In process_inner_cksums, when parsing tunnel packets, inner L4 offset should be
outer_l2_len + outer_l3_len + l2_len + l3_len.
In process_outer_cksums, when parsing tunnel packets, outer L4 offset should be
outer_l2_len + outer_l3_len.
