[dpdk-dev] checksum and vlan insertion seem not working on X520

[Ananyev, Konstantin]

Hi Linc,

Wonder what TX function are you using?
Make sure that you are not using simple TX function that doesn’t support any offloads or multiseg packets.
You need something like that at setup phase:

rte_eth_dev_info_get(port_id, &dev_info);
dev_info.default_txconf.txq_flags = 0;
...
rte_eth_tx_queue_setup(…, &dev_info.default_txconf);
