Hi John, >From rte_mbuf.h: #define PKT_RX_VLAN_PKT (1ULL << 0) /**< RX packet is a 802.1q VLAN packet. */ So yes, in theory it should be set up for vlan packet with both stripping on/off. The problem is that (as far as I know) when VLAN stripping is disabled FVL RXD doesn't contain information does that packet contain a VLAN or not. Don't really know what is the best option in that case: keep things as it is or change the meaning of the VLAN_PKT flag to indicate is mbuf.vlan_tci field is valid or not. Konstantin
