Subject: [dpdk-dev] [PATCH v3 3/3] app/testpmd:change tx_checksum command and csum forwarding engine
Date: Wed, 10 Dec 2014 09:03:23 +0800
Message-ID: <1418173403-30202-4-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1418173403-30202-1-git-send-email-jijiang.liu@intel.com>

The patch enhances the tx_checksum command and reworks csum forwarding engine due to the change of tx_checksum command.
The main changes of the tx_checksum command are listed below,
 
1. add "tx_checksum set tunnel (hw|sw|none) (port-id)" command
 
2. add "tx_checksum set outer-ip (hw|sw) (port-id)" command
 
3. remove the "vxlan" option from the "tx_checksum set(ip|udp|tcp|sctp|vxlan) (hw|sw) (port-id)" command
 
Moreover, replace the TESTPMD_TX_OFFLOAD_VXLAN_CKSUM flag with TESTPMD_TX_OFFLOAD_TUNNEL_CKSUM flag, and add the TESTPMD_TX_OFFLOAD_OUTER_IP_CKSUM and TESTPMD_TX_OFFLOAD_NON_TUNNEL_CKSUM flag.
