> Subject: [PATCH v2] net/i40e: fix forward outer IPv6 VXLAN packets
>
> Testpmd forwards packets in checksum mode that it need to calculate the
> checksum of each layer's protocol. Then it will fill flags and header length
> into
> mbuf.
>
> In process_outer_cksums, HW calculates the outer checksum if tx_offloads
> contains outer UDP checksum otherwise SW calculates the outer checksum.
>
> When tx_offloads contains outer UDP checksum or outer IPv4 checksum,
> mbuf will be filled with correct header length.
>
> This patch added outer UDP checksum in tx_offload_capa and
> I40E_TX_OFFLOAD_MASK, when we set csum hw outer-udp on that the
> engine can forward outer IPv6 VXLAN packets.
