+ IPVLAN Driver HOWTO
+
+Initial Release:
+ Mahesh Bandewar <maheshb AT google.com>
+
+1. Introduction:
+ This is conceptually very similar to the macvlan driver with one major
+exception of using L3 for mux-ing /demux-ing among slaves. This property makes
+the master device share the L2 with it's slave devices. I have developed this
+driver in conjuntion with network namespaces and not sure if there is use case
+outside of it.
+
+
+2. Building and Installation:
+ In order to build the driver, please select the config item CONFIG_IPVLAN.
+The driver can be built into the kernel (CONFIG_IPVLAN=y) or as a module
+(CONFIG_IPVLAN=m).
+
+
+3. Configuration:
+ There are no module parameters for this driver and it can be configured
+using IProute2/ip utility.
+
+ ip link add link <master-dev> <slave-dev> type ipvlan mode { l2 | L3 }
+
+ e.g. ip link add link ipvl0 eth0 type ipvlan mode l2
+
+
+4. Operating modes:
+ IPvlan has two modes of operation - L2 and L3. For a given master device,
+you can select one of these two modes and all slaves on that master will
+operate in the same (selected) mode. The RX mode is almost identical except
+that in L3 mode the slaves wont receive any multicast / broadcast traffic.
+L3 mode is more restrictive since routing is controlled from the other (mostly)
+default namespace.
+
+4.1 L2 mode:
+ In this mode TX processing happens on the stack instance attached to the
+slave device and packets are switched and queued to the master device to send
+out. In this mode the slaves will RX/TX multicast and broadcast (if applicable)
+as well.
+
+4.2 L3 mode:
+ In this mode TX processing upto L3 happens on the stack instance attached
+to the slave device and packets are switched to the stack instance of the
+master device for the L2 processing and routing from that instance will be
+used before packets are queued on the outbound device. In this mode the slaves
+will not receive nor can send multicast / broadcast traffic.
+
+
+5. What to choose (macvlan vs. ipvlan)?
+ These two devices are very similar in many regards and the specific use
+case could very well define which device to choose. if one of the following
+situations defines your use case then you can choose to use ipvlan -
+ (a) The Linux host that is connected to the external switch / router has
+policy configured that allows only one mac per port.
+ (b) No of virtual devices created on a master exceed the mac capacity and
+puts the NIC in promiscous mode and degraded performance is a concern.
+ (c) If the slave device is to be put into the hostile / untrusted network
+namespace where L2 on the slave could be changed / misused.
+
+
+6. Example configuration:
+
+ +=============================================================+
+ | Host: host1 |
+ | |
+ | +----------------------+ +----------------------+ |
+ | | NS:ns0 | | NS:ns1 | |
+ | | | | | |
+ | | | | | |
+ | | ipvl0 | | ipvl1 | |
+ | +----------#-----------+ +-----------#----------+ |
+ | # # |
+ | ################################ |
+ | # eth0 |
+ +==============================#==============================+
+
+
+ (a) Create two network namespaces - ns0, ns1
+ ip netns add ns0
+ ip netns add ns1
+
+ (b) Create two ipvlan slaves on eth0 (master device)
+ ip link add link eth0 ipvl0 type ipvlan mode l2
+ ip link add link eth0 ipvl1 type ipvlan mode l2
+
+ (c) Assign slaves to the respective network namespaces
+ ip link set dev ipvl0 netns ns0
+ ip link set dev ipvl1 netns ns1
+
+ (d) Now switch to the namespace (ns0 or ns1) to configure the slave devices
+ - For ns0
+ (1) ip netns exec ns0 bash
+ (2) ip link set dev ipvl0 up
+ (3) ip link set dev lo up
+ (4) ip -4 addr add 127.0.0.1 dev lo
+ (5) ip -4 addr add $IPADDR dev ipvl0
+ (6) ip -4 route add default via $ROUTER dev ipvl0
+ - For ns1
+ (1) ip netns exec ns1 bash
+ (2) ip link set dev ipvl1 up
+ (3) ip link set dev lo up
+ (4) ip -4 addr add 127.0.0.1 dev lo
+ (5) ip -4 addr add $IPADDR dev ipvl1

phyaddr: to manually provide the physical address to the PHY device;
The xmit method is invoked when the kernel needs to transmit a packet; it sets
the descriptors in the ring and informs the DMA engine that there is a packet
ready to be transmitted.
-Once the controller has finished transmitting the packet, an interrupt is
-triggered; So the driver will be able to release the socket buffers.
By default, the driver sets the NETIF_F_SG bit in the features field of the

4.3) Interrupt Mitigation
The driver is able to mitigate the number of its DMA interrupts
using NAPI for the reception on chips older than the 3.50.
New chips have an HW RX-Watchdog used for this mitigation.
-
-On Tx-side, the mitigation schema is based on a SW timer that calls the
-tx function (stmmac_tx) to reclaim the resource after transmitting the
-frames.
-Also there is another parameter (like a threshold) used to program
-the descriptors avoiding to set the interrupt on completion bit in
-when the frame is sent (xmit).
-
Mitigation parameters can be tuned by ethtool.

+ port1 port2 port3 port4 MNGMNT | PCI-E |

+ | | | | | |
+ | | +- PCI-E -+ | |
+ | +------- MII -------+ |
+ +------------- MII ------------+
+
+In this example, there are two independent lines between the switch silicon
+and CPU. NIC0 and NIC1 drivers are not aware of a switch presence. They are
+separate from the switch driver. SOME switch chip is by managed by a driver
+via PCI-E device MNGMNT. Note that MNGMNT device, NIC0 and NIC1 may be
+connected to some other type of bus.
+
+Now, for the previous example show the representation in kernel:
+
+ +----------------------------+ +---------------+
+ | SOME switch chip | | CPU |
+ +----------------------------+ +---------------+
+ sw0p0 sw0p1 sw0p2 sw0p3 MNGMNT | PCI-E |
+ | | | | | +---------------+
+ PHY PHY | | | | eth0 eth1
+ | | | | | |
+ | | +- PCI-E -+ | |
+ | +------- MII -------+ |
+ +------------- MII ------------+
+
+Lets call the example switch driver for SOME switch chip "SOMEswitch". This
+driver takes care of PCI-E device MNGMNT. There is a netdevice instance sw0pX
+created for each port of a switch. These netdevices are instances
+of "SOMEswitch" driver. sw0pX netdevices serve as a "representation"
+of the switch chip. eth0 and eth1 are instances of some other existing driver.
+
+The only difference of the switch-port netdevice from the ordinary netdevice
+is that is implements couple more NDOs:
+
+ ndo_switch_parent_id_get - This returns the same ID for two port netdevices
+ of the same physical switch chip. This is
+ mandatory to be implemented by all switch drivers
+ and serves the caller for recognition of a port
+ netdevice.
+ ndo_switch_parent_* - Functions that serve for a manipulation of the switch
+ chip itself (it can be though of as a "parent" of the
+ port, therefore the name). They are not port-specific.
+ Caller might use arbitrary port netdevice of the same
+ switch and it will make no difference.
+ ndo_switch_port_* - Functions that serve for a port-specific manipulation.
1.3.3 Timestamp Options
-The interface supports one option
+The interface supports the options
SOF_TIMESTAMPING_OPT_ID:
have multiple concurrent timestamping requests outstanding. Packets
can be reordered in the transmit path, for instance in the packet
scheduler. In that case timestamps will be queued onto the error
- queue out of order from the original send() calls. This option
- embeds a counter that is incremented at send() time, to order
- timestamps within a flow.
+ queue out of order from the original send() calls. It is not always
+ possible to uniquely match timestamps to the original send() calls
+ based on timestamp order or payload inspection alone, then.
+
+ This option associates each packet at send() with a unique
+ identifier and returns that along with the timestamp. The identifier
+ is derived from a per-socket u32 counter (that wraps). For datagram
+ sockets, the counter increments with each sent packet. For stream
+ sockets, it increments with every byte.
+
+ The counter starts at zero. It is initialized the first time that
+ the socket option is enabled. It is reset each time the option is
+ enabled after having been disabled. Resetting the counter does not
+ change the identifiers of existing packets in the system.
This option is implemented only for transmit timestamps. There, the
timestamp is always looped along with a struct sock_extended_err.
The option modifies field ee_data to pass an id that is unique
among all possibly concurrently outstanding timestamp requests for
- that socket. In practice, it is a monotonically increasing u32
- (that wraps).
+ that socket.
+
+
+SOF_TIMESTAMPING_OPT_CMSG:
- In datagram sockets, the counter increments on each send call. In
- stream sockets, it increments with every byte.
+ Support recv() cmsg for all timestamped packets. Control messages
+ are already supported unconditionally on all packets with receive
+ timestamps and on IPv6 packets with transmit timestamp. This option
+ extends them to IPv4 packets with transmit timestamp. One use case
+ is to correlate packets with their egress device, by enabling socket
+ option IP_PKTINFO simultaneously.

* since there won't be any time to beacon before the switch anyway.
+ * @pre_channel_switch: This is an optional callback that is called
+ * before a channel switch procedure is started (ie. when a STA
+ * gets a CSA or an userspace initiated channel-switch), allowing
+ * the driver to prepare for the channel switch.
+ * @post_channel_switch: This is an optional callback that is called
+ * after a channel switch procedure is completed, allowing the
+ * driver to go back to a normal configuration.
*
* @join_ibss: Join an IBSS (on an IBSS interface); this is called after all
* information in bss_conf is set up and the beacon can be retrieved. A
* @get_expected_throughput: extract the expected throughput towards the
* specified station. The returned value is expressed in Kbps. It returns 0
* if the RC algorithm does not have proper data to provide.
+ *
+ * @get_txpower: get current maximum tx power (in dBm) based on configuration
+ * and hardware limits.
+ *
+ * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
+ * is responsible for continually initiating channel-switching operations
+ * and returning to the base channel for communication with the AP. The
+ * driver receives a channel-switch request template and the location of
+ * the switch-timing IE within the template as part of the invocation.
+ * The template is valid only within the call, and the driver can
+ * optionally copy the skb for further re-use.
+ * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
+ * peers must be on the base channel when the call completes.
+ * @tdls_recv_channel_switch: a TDLS channel-switch related frame (request or
+ * response) has been received from a remote peer. The driver gets
+ * parameters parsed from the incoming frame and may use them to continue
+ * an ongoing channel-switch operation. In addition, a channel-switch
+ * response template is provided, together with the location of the
+ * switch-timing IE within the template. The skb can only be used within
+ * the function call.

*
- * This function takes in an Ethernet header and encapsulates it with suitable
