Subject: [PATCH v2 04/10] net/txgbe: fix packet type to parse from offload flags
Date: Thu, 2 Feb 2023 17:21:26 +0800 [thread overview]
Message-ID: <20230202092132.3271910-5-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20230202092132.3271910-1-jiawenwu@trustnetic.com>
Context descriptors which contains the length of each packet layer and
the packet type are needed when Tx checksum offload or TSO is on. If the
packet type and length do not strictly match, it will cause Tx ring hang.
In some external applications, developers may fill in wrong packet_type
in rte_mbuf for Tx path. For example, they encap/decap the packets but
did not refill the packet_type. To prevent this, change it to parse from
ol_flags.
Fixes: ca46fcd753b1 ("net/txgbe: support Tx with hardware offload")
