Subject: [PATCH] app/testpmd: fix IPv6 tunnel checksum
[ upstream commit 3c32113a1aac6d399b1850cd24c42df71c1558cd ]
When ipv6 packet is tunnel packet, "PKT_TX_OUTER_IPV6" flag must
be set, to let prepare the correct mbuf meta data for tx forward.
Fixes: 2b76648872c9 ("net/e1000: add Tx preparation")
