De Lara Guarch, Pablo Nov. 27, 2014, 7:47 p.m. UTC
Moved commands in testpmd UG to set queue rates
to match order in testpmd command help.

Created new section "Filters" to match that
same section in testpmd UG, and moved all
commands related to it there.

+    These threshold options are also available from the command-line.
 
-*   high: this SYN filter has higher priority than other filters.
+Flow Director Functions
+-----------------------
 
-*   low: this SYN filter has lower priority than other filters.
+The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
 
-*   queue_id: The receive queue associated with this SYN filter
+Two types of filtering are supported which are referred to as Perfect Match and Signature filters:
 
-Example:
+*   Perfect match filters.
+    The hardware checks a match between the masked fields of the received packets and the programmed filters.
 
-.. code-block:: console
+*   Signature filters.
+    The hardware checks a match between a hash-based signature of the masked fields of the received packet.
 
-    testpmd> add_syn_filter 0 priority high queue 3,
+The Flow Director filters can match the following fields in a packet:
 
-remove_syn_filter
-~~~~~~~~~~~~~~~~~
+*   Source IP and destination IP addresses.
 
-Remove SYN filter
+*   Source port and destination port numbers (for UDP and TCP packets).
 
-remove_syn_filter (port_id)
+*   IPv4/IPv6 and UDP/ TCP/SCTP protocol match.
 
-get_syn_filter
-~~~~~~~~~~~~~~
+*   VLAN header.
 
-Get and display SYN filter
+*   Flexible 2-byte tuple match anywhere in the first 64 bytes of the packet.
 
-get_syn_filter (port_id)
+The Flow Director can also mask out parts of all of these fields so that filters are only applied to certain fields
+or parts of the fields.
+For example it is possible to mask out sub-nets of IP addresses or to ignore VLAN headers.
 
-Example:
+In the following sections, several common parameters are used in the Flow Director filters.
+These are explained below:
 
-.. code-block:: console
+*   src: A pair of source address values. The source IP, in IPv4 or IPv6 format, and the source port:
 
-    testpmd> get_syn_filter 0
+    src 192.168.0.1 1024
 
-    syn filter: on, priority: high, queue: 3
+    src 2001:DB8:85A3:0:0:8A2E:370:7000 1024
 
-add_flex_filter
-~~~~~~~~~~~~~~~
+*   dst: A pair of destination address values. The destination IP, in IPv4 or IPv6 format, and the destination port.
 
-Add a Flex filter,
-which recognizes any arbitrary pattern within the first 128 bytes of the packet
-and routes packets into one of the receive queues.
+*   flexbytes: A 2-byte tuple to be matched within the first 64 bytes of a packet.
 
-add_flex_filter (port_id) len (len_value) bytes (bytes_string) mask (mask_value)
-priority (prio_value) queue (queue_id) index (idx)
+The offset where the match occurs is set by the --pkt-filter-flexbytes-offset command-line parameter
+and is counted from the first byte of the destination Ethernet MAC address.
+The default offset is 0xC bytes, which is the "Type" word in the MAC header.
+Typically, the flexbyte value is set to 0x0800 to match the IPv4 MAC type or 0x86DD to match IPv6.
+These values change when a VLAN tag is added.
 
-The available information parameters are:
+*   vlan: The VLAN header to match in the packet.
 
-*   port_id: the port which the Flex filter assigned on.
+*   queue: The index of the RX queue to route matched packets to.
 
-*   len_value: filter length in byte, no greater than 128.
+*   soft: The 16-bit value in the MBUF flow director ID field for RX packets matching the filter.
 
-*   bytes_string: a sting in format of octal, means the value the flex filter need to match.
+add_signature_filter
+~~~~~~~~~~~~~~~~~~~~
 
-*   mask_value: a sting in format of octal, bit 1 means corresponding byte in DWORD participates in the match.
+Add a signature filter:
 
-*   prio_value: the priority of this filter.
+# Command is displayed on several lines for clarity.
 
-*   queue_id: The receive queue associated with this Flex filter.

+Set the transmission policy for a Link Bonding device when it is in Balance XOR mode:
 
-Flow Director Functions
------------------------
+set bonding xmit_balance_policy (port_id) (l2|l23|l34)
 
-The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
+For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports )
 
-Two types of filtering are supported which are referred to as Perfect Match and Signature filters:
+.. code-block:: console
 
-*   Perfect match filters.
-    The hardware checks a match between the masked fields of the received packets and the programmed filters.
+    testpmd> set bonding xmit_balance_policy 10 l34
 
-*   Signature filters.
-    The hardware checks a match between a hash-based signature of the masked fields of the received packet.
 
-The Flow Director filters can match the following fields in a packet:
+set bonding mon_period
+~~~~~~~~~~~~~~~~~~~~~~
 
-*   Source IP and destination IP addresses.
+Set the link status monitoring polling period in milliseconds for a bonding devicie.
 
-*   Source port and destination port numbers (for UDP and TCP packets).
+This adds support for PMD slave devices which do not support link status interrupts.
+When the mon_period is set to a value greater than 0 then all PMD's which do not support
+link status ISR will be queried every polling interval to check if their link status has changed.
 
-*   IPv4/IPv6 and UDP/ TCP/SCTP protocol match.
+set bonding mon_period (port_id) (value)
 
-*   VLAN header.
+For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms
 
-*   Flexible 2-byte tuple match anywhere in the first 64 bytes of the packet.
+.. code-block:: console
 
-The Flow Director can also mask out parts of all of these fields so that filters are only applied to certain fields
-or parts of the fields.
-For example it is possible to mask out sub-nets of IP addresses or to ignore VLAN headers.
+    testpmd> set bonding mon_period 5 150
 
-In the following sections, several common parameters are used in the Flow Director filters.
-These are explained below:
 
-*   src: A pair of source address values. The source IP, in IPv4 or IPv6 format, and the source port:
+show bonding config
+~~~~~~~~~~~~~~~~~~~
 
-    src 192.168.0.1 1024
+Show the current configuration of a Link Bonding device:
 
-    src 2001:DB8:85A3:0:0:8A2E:370:7000 1024
+show bonding config (port id)
 
-*   dst: A pair of destination address values. The destination IP, in IPv4 or IPv6 format, and the destination port.
+For example,
+to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
+in balance mode with a transmission policy of layer 2+3.
 
-*   flexbytes: A 2-byte tuple to be matched within the first 64 bytes of a packet.
+.. code-block:: console
 
-The offset where the match occurs is set by the --pkt-filter-flexbytes-offset command-line parameter
-and is counted from the first byte of the destination Ethernet MAC address.
-The default offset is 0xC bytes, which is the "Type" word in the MAC header.
-Typically, the flexbyte value is set to 0x0800 to match the IPv4 MAC type or 0x86DD to match IPv6.
-These values change when a VLAN tag is added.
+    testpmd> show bonding config 9
+        Bonding mode: 2
+        Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
+        Slaves (3): [1 3 4]
+        Active Slaves (3): [1 3 4]
+        Primary: [3]
 
-*   vlan: The VLAN header to match in the packet.
+Register Functions
+------------------
 
-*   queue: The index of the RX queue to route matched packets to.
+The Register functions can be used to read from and write to registers on the network card referenced by a port number.
+This is mainly useful for debugging purposes.
+Reference should be made to the appropriate datasheet for the network card for details on the register addresses
+and fields that can be accessed.

-read regfield (port_id) (address) (bit_x) (bit_y)
+Add a Flex filter,
+which recognizes any arbitrary pattern within the first 128 bytes of the packet
+and routes packets into one of the receive queues.
 
-For example, reading the lowest two bits from the register in the example above:
+add_flex_filter (port_id) len (len_value) bytes (bytes_string) mask (mask_value)
+priority (prio_value) queue (queue_id) index (idx)
 
-.. code-block:: console
+The available information parameters are:
 
-    testpmd> read regfield 0 0xEE00 0 1
-    port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)
+*   port_id: the port which the Flex filter assigned on.
 
-read regbit
-~~~~~~~~~~~
+*   len_value: filter length in byte, no greater than 128.
 
-Display a single port register bit:
+*   bytes_string: a sting in format of octal, means the value the flex filter need to match.
 
-read regbit (port_id) (address) (bit_x)
+*   mask_value: a sting in format of octal, bit 1 means corresponding byte in DWORD participates in the match.
 
-For example, reading the lowest bit from the register in the example above:
+*   prio_value: the priority of this filter.
 
-.. code-block:: console
+*   queue_id: The receive queue associated with this Flex filter.
 
-    testpmd> read regbit 0 0xEE00 0
-    port 0 PCI register at offset 0xEE00: bit 0=1
+*   index: the index of this Flex filter
 
-write reg
-~~~~~~~~~
+Example:
 
-Set the value of a port register:
+.. code-block:: console
 
-write reg (port_id) (address) (value)
+   testpmd> add_flex_filter 0 len 16 bytes 0x00000000000000000000000008060000 mask 000C priority 3 queue 3 index 0
 
-For example, to clear a register:
+Assign a packet whose 13th and 14th bytes are 0x0806 to queue 3.
 
-.. code-block:: console
+remove_flex_filter
+~~~~~~~~~~~~~~~~~~
 
-    testpmd> write reg 0 0xEE00 0x0
-    port 0 PCI register at offset 0xEE00: 0x00000000 (0)
+Remove a Flex filter
 
-write regfield
-~~~~~~~~~~~~~~
+remove_flex_filter (port_id) index (idx)
 
-Set bit field of a port register:
+get_flex_filter
+~~~~~~~~~~~~~~~
 
-write regfield (port_id) (address) (bit_x) (bit_y) (value)
+Get and display a Flex filter
 
-For example, writing to the register cleared in the example above:
+get_flex_filter (port_id) index (idx)
+
+Example:
 
 .. code-block:: console
 
-    testpmd> write regfield 0 0xEE00 0 1 2
-    port 0 PCI register at offset 0xEE00: 0x00000002 (2)
+    testpmd> get_flex_filter 0 index 0
 
-write regbit
-~~~~~~~~~~~~
+    filter[0]:
 
-Set single bit value of a port register:
+        length: 16
 
-write regbit (port_id) (address) (bit_x) (value)
+        dword[]: 0x00000000 00000000 00000000 08060000 00000000 00000000 00000000

-For example, to set the high bit in the register from the example above:
+        mask[]:
+    0b0000000000001100000000000000000000000000000000000000000000000000000000
