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.
