Subject: [PATCH v1 1/1] net: fix inner L2 length for GRE and NVGRE
Date: Wed, 29 Oct 2025 18:35:23 +0530 [thread overview]
Message-ID: <20251029130523.1642847-1-rkudurumalla@marvell.com> (raw)
Inner l2 length needs to be updated to include GRE and NVGRE
headers. Not updating this would cause failures for applications
which would be expecting l2_len field to be valid for
inner checksum offload cases.
Fixes: 76730c7b9b5a ("app/testpmd: use packet type parsing API")
