Subject: [dpdk-dev] [PATCH v1] net: fix TSO packet checksum incorrect
Date: Tue, 28 Jul 2020 08:55:31 +0000
Message-ID: <20200728085531.204296-1-yuying.zhang@intel.com> (raw)

The ol_flags check lacks of PKT_TX_IPV6 which causes checksum
flag configuration error while IPv6/TCP TSO packet is sent.
This patch fixes the issue using PKT_TX_OFFLOAD_MASK.

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