This is a fix to the i40e_rx_vec_dev_conf_condition_check_default() function.
The issue is caused because there is no check on the hw_vlan_extend flag at present.
This is the correct fixline for that function.
ca74903b75 (Jianbo Liu 2016-10-14 09:30:00 +0530 221) i40e_rx_vec_dev_conf_condition_check_default(struct rte_eth_dev *dev)
I will send a v2 as I should have added the "Cc: stable@dpdk.org" line.
Regards,
Bernard.
