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: 399421100e08 ("net/i40e: fix missing mbuf fast free offload")
