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.
Fixes: 7497d3e2f777 ("net/i40e: convert to new Tx offloads API")
