When VLAN is offloaded the driver must set the PKT_RX_VLAN_STRIPPED flag. Actually, several drivers have the same bug, only most of the Intel drivers look right. Any driver that sets vlan_tci is probably stripping the tag, and should be setting RX_VLAN_STRIPPED. To quote rte_mbuf.h: /** * The RX packet is a 802.1q VLAN packet, and the tci has been * saved in in mbuf->vlan_tci. * If the flag PKT_RX_VLAN_STRIPPED is also present, the VLAN * header has been stripped from mbuf data, else it is still * present. */ Fixes: 2eb53b134aae ("net/bnxt: add initial Rx code") Cc: stable@dpdk.org Signed-off-by: Stephen Hemminger Acked-by: Ajit Khaparde --- diff --git a/drivers/net/bnxt/bnxt_rxr.c b/drivers/net/bnxt/bnxt_rxr.c index 1bfc63d930..dc695e1777 100644 --- a/drivers/net/bnxt/bnxt_rxr.c +++ b/drivers/net/bnxt/bnxt_rxr.c @@ -154,7 +154,7 @@ static void bnxt_tpa_start(struct bnxt_rx_queue *rxq, if (tpa_start1->flags2 & rte_cpu_to_le_32(RX_TPA_START_CMPL_FLAGS2_META_FORMAT_VLAN)) { mbuf->vlan_tci = rte_le_to_cpu_32(tpa_start1->metadata); - mbuf->ol_flags |= PKT_RX_VLAN; + mbuf->ol_flags |= PKT_RX_VLAN | PKT_RX_VLAN_STRIPPED; } if (likely(tpa_start1->flags2 & rte_cpu_to_le_32(RX_TPA_START_CMPL_FLAGS2_L4_CS_CALC))) @@ -437,7 +437,7 @@ static int bnxt_rx_pkt(struct rte_mbuf **rx_pkt, (RX_PKT_CMPL_METADATA_VID_MASK | RX_PKT_CMPL_METADATA_DE | RX_PKT_CMPL_METADATA_PRI_MASK); - mbuf->ol_flags |= PKT_RX_VLAN; + mbuf->ol_flags |= PKT_RX_VLAN | PKT_RX_VLAN_STRIPPED; } if (likely(RX_CMP_IP_CS_OK(rxcmp1)))
