From: Ferruh Yigit Date: Wed, 3 Oct 2018 15:19:12 +0000 (+0100) Subject: mbuf: clarify QinQ flag usage X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b2fd0273897e9254d0ae7965fbd4e5f4e9618d1d;p=dpdk.git mbuf: clarify QinQ flag usage Update implementation that when PKT_RX_QINQ_STRIPPED mbuf ol_flags set by PMD, PKT_RX_QINQ, PKT_RX_VLAN_STRIPPED & PKT_RX_VLAN should be also set. Clarify mbuf documentations that when PKT_RX_QINQ set PKT_RX_VLAN also should be set. So that appllication can rely on PKT_RX_QINQ flag to access both mbuf.vlan_tci & mbuf.vlan_tci_outer Signed-off-by: Ferruh Yigit Reviewed-by: Andrew Rybchenko Acked-by: Olivier Matz --- diff --git a/app/test-pmd/rxonly.c b/app/test-pmd/rxonly.c index e8d226624a..41db0ffb4f 100644 --- a/app/test-pmd/rxonly.c +++ b/app/test-pmd/rxonly.c @@ -130,11 +130,11 @@ pkt_burst_receive(struct fwd_stream *fs) } if (ol_flags & PKT_RX_TIMESTAMP) printf(" - timestamp %"PRIu64" ", mb->timestamp); - if (ol_flags & PKT_RX_VLAN) - printf(" - VLAN tci=0x%x", mb->vlan_tci); - if (ol_flags & PKT_RX_QINQ_STRIPPED) + if (ol_flags & PKT_RX_QINQ) printf(" - QinQ VLAN tci=0x%x, VLAN tci outer=0x%x", mb->vlan_tci, mb->vlan_tci_outer); + else if (ol_flags & PKT_RX_VLAN) + printf(" - VLAN tci=0x%x", mb->vlan_tci); if (mb->packet_type) { rte_get_ptype_name(mb->packet_type, buf, sizeof(buf)); printf(" - hw ptype: %s", buf); diff --git a/doc/guides/nics/features.rst b/doc/guides/nics/features.rst index d42489b6db..4a946251a1 100644 --- a/doc/guides/nics/features.rst +++ b/doc/guides/nics/features.rst @@ -528,7 +528,7 @@ Supports VLAN offload to hardware. * **[uses] rte_eth_rxconf,rte_eth_rxmode**: ``offloads:DEV_RX_OFFLOAD_VLAN_STRIP,DEV_RX_OFFLOAD_VLAN_FILTER,DEV_RX_OFFLOAD_VLAN_EXTEND``. * **[uses] rte_eth_txconf,rte_eth_txmode**: ``offloads:DEV_TX_OFFLOAD_VLAN_INSERT``. * **[implements] eth_dev_ops**: ``vlan_offload_set``. -* **[provides] mbuf**: ``mbuf.ol_flags:PKT_RX_VLAN_STRIPPED``, ``mbuf.vlan_tci``. +* **[provides] mbuf**: ``mbuf.ol_flags:PKT_RX_VLAN_STRIPPED``, ``mbuf.ol_flags:PKT_RX_VLAN`` ``mbuf.vlan_tci``. * **[provides] rte_eth_dev_info**: ``rx_offload_capa,rx_queue_offload_capa:DEV_RX_OFFLOAD_VLAN_STRIP``, ``tx_offload_capa,tx_queue_offload_capa:DEV_TX_OFFLOAD_VLAN_INSERT``. * **[related] API**: ``rte_eth_dev_set_vlan_offload()``, @@ -545,8 +545,9 @@ Supports QinQ (queue in queue) offload. * **[uses] rte_eth_rxconf,rte_eth_rxmode**: ``offloads:DEV_RX_OFFLOAD_QINQ_STRIP``. * **[uses] rte_eth_txconf,rte_eth_txmode**: ``offloads:DEV_TX_OFFLOAD_QINQ_INSERT``. * **[uses] mbuf**: ``mbuf.ol_flags:PKT_TX_QINQ_PKT``. -* **[provides] mbuf**: ``mbuf.ol_flags:PKT_RX_QINQ_STRIPPED``, ``mbuf.vlan_tci``, - ``mbuf.vlan_tci_outer``. +* **[provides] mbuf**: ``mbuf.ol_flags:PKT_RX_QINQ_STRIPPED``, ``mbuf.ol_flags:PKT_RX_QINQ``, + ``mbuf.ol_flags:PKT_RX_VLAN_STRIPPED``, ``mbuf.ol_flags:PKT_RX_VLAN`` + ``mbuf.vlan_tci``, ``mbuf.vlan_tci_outer``. * **[provides] rte_eth_dev_info**: ``rx_offload_capa,rx_queue_offload_capa:DEV_RX_OFFLOAD_QINQ_STRIP``, ``tx_offload_capa,tx_queue_offload_capa:DEV_TX_OFFLOAD_QINQ_INSERT``. diff --git a/drivers/net/i40e/i40e_rxtx.c b/drivers/net/i40e/i40e_rxtx.c index 7c986d5357..b2819f757b 100644 --- a/drivers/net/i40e/i40e_rxtx.c +++ b/drivers/net/i40e/i40e_rxtx.c @@ -83,7 +83,8 @@ i40e_rxd_to_vlan_tci(struct rte_mbuf *mb, volatile union i40e_rx_desc *rxdp) #ifndef RTE_LIBRTE_I40E_16BYTE_RX_DESC if (rte_le_to_cpu_16(rxdp->wb.qword2.ext_status) & (1 << I40E_RX_DESC_EXT_STATUS_L2TAG2P_SHIFT)) { - mb->ol_flags |= PKT_RX_QINQ_STRIPPED; + mb->ol_flags |= PKT_RX_QINQ_STRIPPED | PKT_RX_QINQ | + PKT_RX_VLAN_STRIPPED | PKT_RX_VLAN; mb->vlan_tci_outer = mb->vlan_tci; mb->vlan_tci = rte_le_to_cpu_16(rxdp->wb.qword2.l2tag2_2); PMD_RX_LOG(DEBUG, "Descriptor l2tag2_1: %u, l2tag2_2: %u", diff --git a/lib/librte_mbuf/rte_mbuf.c b/lib/librte_mbuf/rte_mbuf.c index e714c5a59b..05a5a17fe9 100644 --- a/lib/librte_mbuf/rte_mbuf.c +++ b/lib/librte_mbuf/rte_mbuf.c @@ -297,6 +297,7 @@ const char *rte_get_rx_ol_flag_name(uint64_t mask) case PKT_RX_IEEE1588_PTP: return "PKT_RX_IEEE1588_PTP"; case PKT_RX_IEEE1588_TMST: return "PKT_RX_IEEE1588_TMST"; case PKT_RX_QINQ_STRIPPED: return "PKT_RX_QINQ_STRIPPED"; + case PKT_RX_QINQ: return "PKT_RX_QINQ"; case PKT_RX_LRO: return "PKT_RX_LRO"; case PKT_RX_TIMESTAMP: return "PKT_RX_TIMESTAMP"; case PKT_RX_SEC_OFFLOAD: return "PKT_RX_SEC_OFFLOAD"; diff --git a/lib/librte_mbuf/rte_mbuf.h b/lib/librte_mbuf/rte_mbuf.h index eb11779e75..50a73788d4 100644 --- a/lib/librte_mbuf/rte_mbuf.h +++ b/lib/librte_mbuf/rte_mbuf.h @@ -140,7 +140,7 @@ extern "C" { * The 2 vlans have been stripped by the hardware and their tci are * saved in mbuf->vlan_tci (inner) and mbuf->vlan_tci_outer (outer). * This can only happen if vlan stripping is enabled in the RX - * configuration of the PMD.
