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: [email protected]"  line.

Regards,

Bernard.
