Date: Fri, 12 Feb 2021 03:05:21 +0530 Message-Id: <1613079324-20166-1-git-send-email-sharathv@codeaurora.org> X-Mailer: git-send-email 2.7.4 Precedence: bulk List-ID: X-Mailing-List: netdev@vger.kernel.org This series introduces the MAPv5 packet format. Patch 0 documents the MAPv5. Patch 1 introduces the Mapv5 and the Inline checksum offload for RX. Patch 2 introduces the Mapv5 and the Inline checksum offload for TX. A new checksum header format is used as part of MAPv5. For RX checksum offload, the checksum is verified by the HW and the validity is marked in the checksum header of MAPv5. for TX, the required metadata is filled up so hardware can compute the checksum.
