+PMD drivers adaption for new RXTX offload APIs
+==============================================
+Description
+===========
+
+ Adapt all the Intel drivers for the new RX/TX offload APIs.
+ There're new RX/TX offload APIs accepted in 17.11,
+ These new APIs are more friendly and easier to use.
+ Currently, they co-exist with the old APIs. Some adaption work is
+ here to make the drivers can use the old ones or the new ones.
+ But suppose the target is to let all the NICs support the new APIs
+ and then remove the old ones.
+ So, in driver layer, we can begin to support the new ones and remove
+ the old ones.
+ Eight new commands are added:
+ Rx test commands:
+ 1. testpmd > show port <port_id> rx_offload capabilities
+ 2. testpmd > show port <port_id> rx_offload configuration
+ 3. testmpd > port config <port_id> rx_offload <offload> on|off
+ 4. testpmd > port <port_id> rxq <queue_id> rx_offload <offload> on|off
+ Tx test commands:
+ 1. testpmd > show port <port_id> tx_offload capabilities
+ 2. testpmd > show port <port_id> tx_offload configuration
+ 3. testmpd > port config <port_id> tx_offload <offload> on|off
+ 4. testpmd > port <port_id> txq <queue_id> tx_offload <offload> on|off
+
+Prerequisites
+=============
+
+1. Hardware:
+ FVL/NNT
+
+2. Software:
+ dpdk: http://dpdk.org/git/dpdk
+ scapy: http://www.secdev.org/projects/scapy/
+
+3. Bind the pf port to dpdk driver::
+
+ ./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1
+
+Notes: There are different capabilities between i40e and ixgbe.
+So define different test cases for the two types of NIC.
+There is no rx_offload per_queue parameter in i40e setting now.
+There is no tx_offload per_queue parameter in ixgbe setting now.
+There are some different printing in general cases between NNT and FVL,
+I just show the printing of NNT.
+
+Test case: NNT Rx offload per-queue setting
+===========================================
+
+1. Start testpmd::
+
+ ./testpmd -c f -n 4 -- -i --rxq=4 --txq=4
+ testpmd> set fwd mac
+ testpmd> set verbose 1
+ testpmd> show port info all
+ VLAN offload:
+ strip off
+
+2. Get the rx_offload capability and configuration::
+
+ testpmd> show port 0 rx_offload capabilities
+ Rx Offloading Capabilities of port 0 :
+ Per Queue : VLAN_STRIP
+ Per Port : IPV4_CKSUM UDP_CKSUM TCP_CKSUM TCP_LRO MACSEC_STRIP VLAN_FILTER VLAN_EXTEND JUMBO_FRAME CRC_STRIP SCATTER SECURITY KEEP_CRC
+
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : CRC_STRIP
+ Queue[ 0] :
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] :
+
+3. Enable vlan_strip per_queue::
+
+ testpmd> port stop 0
+ testpmd> port 0 rxq 0 rx_offload vlan_strip on
+ testpmd> port 0 rxq 2 rx_offload vlan_strip on
+ testpmd> port start 0
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : CRC_STRIP
+ Queue[ 0] : VLAN_STRIP
+ Queue[ 1] :
+ Queue[ 2] : VLAN_STRIP
+ Queue[ 3] :
+
+ testpmd> show port info 0
+ VLAN offload:
+ strip on
+
+4. Send two packets::
+
+ pkt1 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(vlan=1)/IP(src="192.168.0.1", dst="192.168.0.3")/UDP(sport=33,dport=34)/Raw('x'*20)
+ pkt2 = Ether(dst="00:00:00:00:01:00", src="00:02:00:00:00:01")/Dot1Q(vlan=1)/IP(src="192.168.0.2", dst="192.168.0.3")/UDP(sport=33,dport=34)/Raw('x'*20)
+
+ Port0 receive the two packets in queue2 and queue3.
+ Queue2 should capture strip vlan information like "VLAN tci=0x1" and "PKT_RX_VLAN_STRIPPED",
+ queue3 doesn't support vlan strip.
+
+ If set "set fwd mac",
+ Check the tester port connected to port1 which receive the forwarded packet
+ So you can check that there is vlan id in pkt1, while there is not vlan id in pkt2.
+ The result is consistent to the DUT port receive packets.
+
+5. Disable vlan_strip per_queue::
+
+ testpmd> port stop 0
+ testpmd> port 0 rxq 3 rx_offload vlan_strip on
+ testpmd> port 0 rxq 2 rx_offload vlan_strip off
+ testpmd> port start 0
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : CRC_STRIP
+ Queue[ 0] : VLAN_STRIP
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] : VLAN_STRIP
+
+ Send the same packets,
+ Queue3 should capture strip vlan information like "VLAN tci=0x1" and "PKT_RX_VLAN_STRIPPED",
+ queue2 doesn't support vlan strip.
+
+6. Enable vlan_strip per_port::
+
+ testpmd> port stop 0
+ testpmd> port config 0 rx_offload vlan_strip on
+ testpmd> port start 0
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : VLAN_STRIP CRC_STRIP
+ Queue[ 0] : VLAN_STRIP
+ Queue[ 1] : VLAN_STRIP
+ Queue[ 2] : VLAN_STRIP
+ Queue[ 3] : VLAN_STRIP
+
+ Send the two packets. queue3 and queue2 both implement vlan_strip
+
+7. Disable vlan_strip per_port::
+
+ testpmd> port stop 0
+ testpmd> port config 0 rx_offload vlan_strip off
+ testpmd> port start 0
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : CRC_STRIP
+ Queue[ 0] :
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] :
+
+ testpmd> show port info 0
+ VLAN offload:
+ strip off
+
+ send the two packets. queue3 and queue2 both don't support vlan_strip
+ Notes: there is no per_queue parameter in i40e driver,
+ so this case is just only for ixgbe.
+
+Test case: Rx offload per-port setting
+===========================================
+
+1. Enable jumboframe when start testpmd::
+
+ ./testpmd -c f -n 4 -- -i --rxq=4 --txq=4 --max-pkt-len=9000
+ testpmd> set fwd rxonly
+ testpmd> set verbose 1
+ testpmd> start
+ testpmd> show port 0 rx_offload capabilities
+ Rx Offloading Capabilities of port 0 :
+ Per Queue : VLAN_STRIP
+ Per Port : IPV4_CKSUM UDP_CKSUM TCP_CKSUM TCP_LRO MACSEC_STRIP VLAN_FILTER VLAN_EXTEND JUMBO_FRAME CRC_STRIP SCATTER SECURITY KEEP_CRC
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : JUMBO_FRAME CRC_STRIP
+ Queue[ 0] :
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] :
+
+2. Improve the tester ports's mtu::
+
+ ifconfig enp131s0f0 mtu 9200
+ ifconfig enp131s0f1 mtu 9200
+
+ Send a jumboframe packet::
+
+ pkt1 = Ether(dst="52:54:00:00:00:01", src="52:00:00:00:00:00")/IP(dst="192.168.0.1", src="192.168.0.2", len=8981)/Raw(load="P"*8961)
+ pkt2 = Ether(dst="52:54:00:00:00:01", src="52:00:00:00:00:00")/IP(dst="192.168.0.1", src="192.168.0.3", len=8981)/Raw(load="P"*8961)
+
+ pkt1 was distributed to queue 1, pkt2 was distributed to queue 0.
+
+3. Failed to disable jumboframe per_queue::
+
+ testpmd> port stop 0
+ testpmd> port 0 rxq 1 rx_offload jumbo_frame off
+ testpmd> port start 0
+ The port can be started normally, but the setting doesn't take effect.
+ Pkt1 still can be distributed to queue 1.
+
+4. Succeed to disable jumboframe per_port::
+
+ testpmd> port stop 0
+ testpmd> port config 0 rx_offload jumbo_frame off
+ testpmd> port start 0
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : CRC_STRIP
+ Queue[ 0] :
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] :
+ testpmd> start
+
+ Send the same two packet, there is no packet received.
+
+5. Failed to enable jumboframe per_queue::
+
+ testpmd> port stop 0
+ testpmd> port 0 rxq 1 rx_offload jumbo_frame on
+ testpmd> port start 0
+ Configuring Port 0 (socket 0)
+ Ethdev port_id=0 rx_queue_id=1, new added offloads 0x800 must be within pre-queue offload capabilities 0x1 in rte_eth_rx_queue_setup()
+ Fail to configure port 0 rx queues
+
+6. Succeed to enable jumboframe per_port::
+
+ testpmd> port stop 0
+ testpmd> port config 0 rx_offload jumbo_frame on
+ testpmd> port start 0
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : JUMBO_FRAME CRC_STRIP
+ Queue[ 0] : JUMBO_FRAME
+ Queue[ 1] : JUMBO_FRAME
+ Queue[ 2] : JUMBO_FRAME
+ Queue[ 3] : JUMBO_FRAME
+
+ Send the same two packet, pkt1 was distributed to queue 1,
+ pkt2 was distributed to queue 0.
+ Notes: There is some difference printing between NNT and FVL,
+ which has no impact to the test result.
+
+Test case: Rx offload per-port setting in command-line
+======================================================
+
+1. Enable rx cksum in command-line::
+
+ ./testpmd -c f -n 4 -- -i --rxq=4 --txq=4 --enable-rx-cksum
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : IPV4_CKSUM UDP_CKSUM TCP_CKSUM CRC_STRIP
+ Queue[ 0] :
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] :
+
+2. Disable the rx cksum per_port::
+
+ testpmd> port stop 0
+ testpmd> port config 0 rx_offload udp_cksum off
+ testpmd> show port 0 rx_offload configuration
+ Rx Offloading Configuration of port 0 :
+ Port : IPV4_CKSUM TCP_CKSUM CRC_STRIP
+ Queue[ 0] :
+ Queue[ 1] :
+ Queue[ 2] :
+ Queue[ 3] :
+ testpmd> port start 0
+
+ The port can start normally.
+ Try this step with "tcp_cksum/ipv4_cksum", the port can start normally.
+
+3. Enable the rx cksum per_port, all the configuration can be set successfully.
+ The port can start normally.
+
+Test case: NNT Rx offload per-queue and per_queue setting
+=========================================================
+
+1. Check all the rx_offload capability::
+
+ testpmd> show port 0 rx_offload capabilities
+ Rx Offloading Capabilities of port 0 :
+ Per Queue : VLAN_STRIP
+ Per Port : IPV4_CKSUM UDP_CKSUM TCP_CKSUM TCP_LRO MACSEC_STRIP VLAN_FILTER VLAN_EXTEND JUMBO_FRAME CRC_STRIP SCATTER SECURITY KEEP_CRC
+
+2. Enable and disable per_port and per_queue capabilities::
+
+ TCP_LRO MACSEC_STRIP VLAN_FILTER VLAN_EXTEND CRC_STRIP SCATTER SECURITY KEEP_CRC
+
+ Check the configuration and the port can start normally.
+ Notes: It's not allowed to set both CRC STRIP and KEEP CRC offload flags.
+ So if you want to config keep_crc on, you must config crc_strip off first.
+
+Test case: Tx offload vlan insert per-port setting
+==================================================
+
+1. Start testpmd::
+
+ ./testpmd -c 0x6 -n 4 -- -i --rxq=4 --txq=4 --port-topology=loop

+ Queue[ 3] : VLAN_INSERT
+ testpmd> start
+
+ There is still not vlan infomation in the received packet.
+
+3. Set the insert vlan ID::
+
+ testpmd> tx_vlan set 0 1
+
+ Tester port0 receive the packet.
+ There is vlan ID in the received packet.
+ The old command can take effect.
+
+4. Disable vlan_insert per_port::
+
+ testpmd> port stop 0
+ testpmd> port config 0 tx_offload vlan_insert off
+ testpmd> port start 0
