Subject: [dpdk-dev] [PATCH v2 1/1] net: fix TSO packets checksum incorrect

The ol_flags check lacks of flag for IPv6 which causes checksum flag configuration error while IPv6/TCP TSO packet is sent.
This patch fixes the issue by adding PKT_TX_TCP_SEG flag.

Fixes: 520059a41aa9 ("net: check fragmented headers in non-debug as well")
