-MRVL Poll Mode Driver
-======================
-
-The MRVL PMD (librte_pmd_mrvl) provides poll mode driver support
-for the Marvell PPv2 (Packet Processor v2) 1/10 Gbps adapter.
-
-Detailed information about SoCs that use PPv2 can be obtained here:
-
-* https://www.marvell.com/embedded-processors/armada-70xx/
-* https://www.marvell.com/embedded-processors/armada-80xx/
-
-.. Note::
-
- Due to external dependencies, this driver is disabled by default. It must
- be enabled manually by setting relevant configuration option manually.
- Please refer to `Config File Options`_ section for further details.
-
-

-
-MUSDK will be installed to `usr/local` under current directory.
-For the detailed build instructions please consult ``doc/musdk_get_started.txt``.
-
-Before the DPDK build process the environmental variable ``LIBMUSDK_PATH`` with
-the path to the MUSDK installation directory needs to be exported.
-
-.. code-block:: console
-
- export LIBMUSDK_PATH=<musdk>/usr/local
- export CROSS=aarch64-linux-gnu-
- make config T=arm64-armv8a-linuxapp-gcc
- sed -ri 's,(MRVL_PMD=)n,\1y,' build/.config
- make
-
-Flow API
---------
-
-PPv2 offers packet classification capabilities via classifier engine which
-can be configured via generic flow API offered by DPDK.
-
-Supported flow actions
-~~~~~~~~~~~~~~~~~~~~~~
-
-Following flow action items are supported by the driver:
-
-* DROP
-* QUEUE
-
-Supported flow items
-~~~~~~~~~~~~~~~~~~~~
-
-Following flow items and their respective fields are supported by the driver:
-
-* ETH
-
- * source MAC
- * destination MAC
- * ethertype
-
-* VLAN
-
- * PCP
- * VID
-
-* IPV4
-
- * DSCP
- * protocol
- * source address
- * destination address
-
-* IPV6
-
- * flow label
- * next header
- * source address
- * destination address
-
-* UDP
-
- * source port
- * destination port
-
-* TCP
-
- * source port
- * destination port
-
-Classifier match engine
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Classifier has an internal match engine which can be configured to
-operate in either exact or maskable mode.
-
-Mode is selected upon creation of the first unique flow rule as follows:
-
-* maskable, if key size is up to 8 bytes.
-* exact, otherwise, i.e for keys bigger than 8 bytes.
-
-Where the key size equals the number of bytes of all fields specified
-in the flow items.
-
-.. table:: Examples of key size calculation
-
- +----------------------------------------------------------------------------+-------------------+-------------+
- | Flow pattern | Key size in bytes | Used engine |
- +============================================================================+===================+=============+
- | ETH (destination MAC) / VLAN (VID) | 6 + 2 = 8 | Maskable |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | VLAN (VID) / IPV4 (source address) | 2 + 4 = 6 | Maskable |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | TCP (source port, destination port) | 2 + 2 = 4 | Maskable |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | VLAN (priority) / IPV4 (source address) | 1 + 4 = 5 | Maskable |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | IPV4 (destination address) / UDP (source port, destination port) | 6 + 2 + 2 = 10 | Exact |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | VLAN (VID) / IPV6 (flow label, destination address) | 2 + 3 + 16 = 21 | Exact |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | IPV4 (DSCP, source address, destination address) | 1 + 4 + 4 = 9 | Exact |
- +----------------------------------------------------------------------------+-------------------+-------------+
- | IPV6 (flow label, source address, destination address) | 3 + 16 + 16 = 35 | Exact |
- +----------------------------------------------------------------------------+-------------------+-------------+
-
-From the user perspective maskable mode means that masks specified
-via flow rules are respected. In case of exact match mode, masks
-which do not provide exact matching (all bits masked) are ignored.
-
-If the flow matches more than one classifier rule the first
-(with the lowest index) matched takes precedence.
-
-Flow rules usage example
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Before proceeding run testpmd user application:
-
-.. code-block:: console
-
- ./testpmd --vdev=net_mrvl,iface=eth0,iface=eth2 -c 3 -- -i --p 3 -a --disable-hw-vlan-strip
-
-Example #1
-^^^^^^^^^^
-
-.. code-block:: console
-
- testpmd> flow create 0 ingress pattern eth src is 10:11:12:13:14:15 / end actions drop / end
-
-In this case key size is 6 bytes thus maskable type is selected. Testpmd
-will set mask to ff:ff:ff:ff:ff:ff i.e traffic explicitly matching
-above rule will be dropped.
-
-Example #2
-^^^^^^^^^^
-
-.. code-block:: console
-
- testpmd> flow create 0 ingress pattern ipv4 src spec 10.10.10.0 src mask 255.255.255.0 / tcp src spec 0x10 src mask 0x10 / end action drop / end
-
-In this case key size is 8 bytes thus maskable type is selected.
-Flows which have IPv4 source addresses ranging from 10.10.10.0 to 10.10.10.255
-and tcp source port set to 16 will be dropped.
-
-Example #3
-^^^^^^^^^^
-
-.. code-block:: console
-
- testpmd> flow create 0 ingress pattern vlan vid spec 0x10 vid mask 0x10 / ipv4 src spec 10.10.1.1 src mask 255.255.0.0 dst spec 11.11.11.1 dst mask 255.255.255.0 / end actions drop / end
-
-In this case key size is 10 bytes thus exact type is selected.
-Even though each item has partial mask set, masks will be ignored.
-As a result only flows with VID set to 16 and IPv4 source and destination
-addresses set to 10.10.1.1 and 11.11.11.1 respectively will be dropped.
-
-Limitations
-~~~~~~~~~~~
-
-Following limitations need to be taken into account while creating flow rules:
-
-* For IPv4 exact match type the key size must be up to 12 bytes.
-* For IPv6 exact match type the key size must be up to 36 bytes.
-* Following fields cannot be partially masked (all masks are treated as
- if they were exact):
-
- * ETH: ethertype
- * VLAN: PCP, VID
- * IPv4: protocol
- * IPv6: next header
- * TCP/UDP: source port, destination port
-
-* Only one classifier table can be created thus all rules in the table
- have to match table format. Table format is set during creation of
- the first unique flow rule.
-* Up to 5 fields can be specified per flow rule.
-* Up to 20 flow rules can be added.
-
-For additional information about classifier please consult
-``doc/musdk_cls_user_guide.txt``.
-
-Usage Example
--------------
-
-MRVL PMD requires extra out of tree kernel modules to function properly.
-`musdk_uio` and `mv_pp_uio` sources are part of the MUSDK. Please consult
-``doc/musdk_get_started.txt`` for the detailed build instructions.
-For `mvpp2x_sysfs` please consult ``Documentation/pp22_sysfs.txt`` for the
-detailed build instructions.
-
-.. code-block:: console
-
- insmod musdk_uio.ko
- insmod mv_pp_uio.ko
- insmod mvpp2x_sysfs.ko
-
-Additionally interfaces used by DPDK application need to be put up:
-
-.. code-block:: console
-
- ip link set eth0 up
- ip link set eth2 up
-
-In order to run testpmd example application following command can be used:
-
-.. code-block:: console
-
- ./testpmd --vdev=eth_mrvl,iface=eth0,iface=eth2 -c 7 -- \
- --burst=128 --txd=2048 --rxd=1024 --rxq=2 --txq=2 --nb-cores=2 \

+Building DPDK
+-------------
+
+Driver needs precompiled MUSDK library during compilation.
+
+.. code-block:: console
+
+ export CROSS_COMPILE=<toolchain>/bin/aarch64-linux-gnu-
+ ./bootstrap
+ ./configure --host=aarch64-linux-gnu --enable-bpool-dma=64
+ make install
+
+MUSDK will be installed to `usr/local` under current directory.
+For the detailed build instructions please consult ``doc/musdk_get_started.txt``.
+
+Before the DPDK build process the environmental variable ``LIBMUSDK_PATH`` with
+the path to the MUSDK installation directory needs to be exported.
+
+.. code-block:: console
+
+ export LIBMUSDK_PATH=<musdk>/usr/local
+ export CROSS=aarch64-linux-gnu-
+ make config T=arm64-armv8a-linuxapp-gcc
+ sed -ri 's,(MVPP2_PMD=)n,\1y,' build/.config

+
+Flow API
+--------
+
+PPv2 offers packet classification capabilities via classifier engine which
+can be configured via generic flow API offered by DPDK.
+
+Supported flow actions
+~~~~~~~~~~~~~~~~~~~~~~
+
+Following flow action items are supported by the driver:
+
+* DROP
+* QUEUE
+
+Supported flow items
+~~~~~~~~~~~~~~~~~~~~
+
+Following flow items and their respective fields are supported by the driver:
+
+* ETH
+
+ * source MAC
+ * destination MAC
+ * ethertype
+
+* VLAN
+
+ * PCP
+ * VID
+
+* IPV4
+
+ * DSCP
+ * protocol
+ * source address
+ * destination address
+
+* IPV6
+
+ * flow label
+ * next header
+ * source address
+ * destination address
+
+* UDP
+
+ * source port
+ * destination port
+
+* TCP
+
+ * source port
+ * destination port
+
+Classifier match engine
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Classifier has an internal match engine which can be configured to
+operate in either exact or maskable mode.
+
+Mode is selected upon creation of the first unique flow rule as follows:
+
+* maskable, if key size is up to 8 bytes.
+* exact, otherwise, i.e for keys bigger than 8 bytes.
+
+Where the key size equals the number of bytes of all fields specified
+in the flow items.
+
+.. table:: Examples of key size calculation
+
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | Flow pattern | Key size in bytes | Used engine |
+ +============================================================================+===================+=============+
+ | ETH (destination MAC) / VLAN (VID) | 6 + 2 = 8 | Maskable |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | VLAN (VID) / IPV4 (source address) | 2 + 4 = 6 | Maskable |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | TCP (source port, destination port) | 2 + 2 = 4 | Maskable |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | VLAN (priority) / IPV4 (source address) | 1 + 4 = 5 | Maskable |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | IPV4 (destination address) / UDP (source port, destination port) | 6 + 2 + 2 = 10 | Exact |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | VLAN (VID) / IPV6 (flow label, destination address) | 2 + 3 + 16 = 21 | Exact |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | IPV4 (DSCP, source address, destination address) | 1 + 4 + 4 = 9 | Exact |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+ | IPV6 (flow label, source address, destination address) | 3 + 16 + 16 = 35 | Exact |
+ +----------------------------------------------------------------------------+-------------------+-------------+
+
+From the user perspective maskable mode means that masks specified
+via flow rules are respected. In case of exact match mode, masks
+which do not provide exact matching (all bits masked) are ignored.
+
+If the flow matches more than one classifier rule the first
+(with the lowest index) matched takes precedence.
+
+Flow rules usage example
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Before proceeding run testpmd user application:
+
+.. code-block:: console
+
+ ./testpmd --vdev=eth_mvpp2,iface=eth0,iface=eth2 -c 3 -- -i --p 3 -a --disable-hw-vlan-strip
+
+Example #1
+^^^^^^^^^^
+
+.. code-block:: console
+
+ testpmd> flow create 0 ingress pattern eth src is 10:11:12:13:14:15 / end actions drop / end
+
+In this case key size is 6 bytes thus maskable type is selected. Testpmd
+will set mask to ff:ff:ff:ff:ff:ff i.e traffic explicitly matching
+above rule will be dropped.
+
+Example #2
+^^^^^^^^^^
+
+.. code-block:: console
+
+ testpmd> flow create 0 ingress pattern ipv4 src spec 10.10.10.0 src mask 255.255.255.0 / tcp src spec 0x10 src mask 0x10 / end action drop / end
+
+In this case key size is 8 bytes thus maskable type is selected.
+Flows which have IPv4 source addresses ranging from 10.10.10.0 to 10.10.10.255
+and tcp source port set to 16 will be dropped.
+
+Example #3
+^^^^^^^^^^
+
+.. code-block:: console
+
+ testpmd> flow create 0 ingress pattern vlan vid spec 0x10 vid mask 0x10 / ipv4 src spec 10.10.1.1 src mask 255.255.0.0 dst spec 11.11.11.1 dst mask 255.255.255.0 / end actions drop / end
+
+In this case key size is 10 bytes thus exact type is selected.
+Even though each item has partial mask set, masks will be ignored.
+As a result only flows with VID set to 16 and IPv4 source and destination
+addresses set to 10.10.1.1 and 11.11.11.1 respectively will be dropped.
+
+Limitations
+~~~~~~~~~~~
+
+Following limitations need to be taken into account while creating flow rules:
+
+* For IPv4 exact match type the key size must be up to 12 bytes.
+* For IPv6 exact match type the key size must be up to 36 bytes.
+* Following fields cannot be partially masked (all masks are treated as
+ if they were exact):
+
+ * ETH: ethertype
+ * VLAN: PCP, VID
+ * IPv4: protocol
+ * IPv6: next header
+ * TCP/UDP: source port, destination port
+
+* Only one classifier table can be created thus all rules in the table
+ have to match table format. Table format is set during creation of
+ the first unique flow rule.
+* Up to 5 fields can be specified per flow rule.
+* Up to 20 flow rules can be added.
+
+For additional information about classifier please consult
+``doc/musdk_cls_user_guide.txt``.
+
+Usage Example
+-------------
+
+MVPP2 PMD requires extra out of tree kernel modules to function properly.
+`musdk_uio` and `mv_pp_uio` sources are part of the MUSDK. Please consult
+``doc/musdk_get_started.txt`` for the detailed build instructions.
+For `mvpp2x_sysfs` please consult ``Documentation/pp22_sysfs.txt`` for the
+detailed build instructions.
+
+.. code-block:: console
+
+ insmod musdk_uio.ko
+ insmod mv_pp_uio.ko
+ insmod mvpp2x_sysfs.ko
+
+Additionally interfaces used by DPDK application need to be put up:
+
+.. code-block:: console
+
+ ip link set eth0 up
+ ip link set eth2 up
+
+In order to run testpmd example application following command can be used:
+
+.. code-block:: console
+
+ ./testpmd --vdev=eth_mvpp2,iface=eth0,iface=eth2 -c 7 -- \
+ --burst=128 --txd=2048 --rxd=1024 --rxq=2 --txq=2 --nb-cores=2 \
