Erf... I'm sorry, my mistake, I copy/pasted the log below without
verifying. I saw it while watching the code.

Yes I mean ETH_VLAN_EXTEND_OFFLOAD. By the way, it could even be
replaced ETH_VLAN_*_MASK, but it's the same value. For reference, here
are the definitions from rte_ethdev.h:

 /* Definitions used for VLAN Offload functionality */
 #define ETH_VLAN_STRIP_OFFLOAD   0x0001 /**< VLAN Strip  On/Off */
 #define ETH_VLAN_FILTER_OFFLOAD  0x0002 /**< VLAN Filter On/Off */
 #define ETH_VLAN_EXTEND_OFFLOAD  0x0004 /**< VLAN Extend On/Off */

 /* Definitions used for mask VLAN setting */
 #define ETH_VLAN_STRIP_MASK   0x0001 /**< VLAN Strip  setting mask */
 #define ETH_VLAN_FILTER_MASK  0x0002 /**< VLAN Filter  setting mask*/
 #define ETH_VLAN_EXTEND_MASK  0x0004 /**< VLAN Extend  setting mask*/


I'll submit another patch with ETH_VLAN_EXTEND_OFFLOAD.
Thanks Ferruh.
