- *
- * This module implements the virtual ethernet device for iSeries LPAR
- * Linux. It uses hypervisor message passing to implement an
- * ethernet-like network device communicating between partitions on
- * the iSeries.
- *
- * The iSeries LPAR hypervisor currently allows for up to 16 different
- * virtual ethernets. These are all dynamically configurable on
- * OS/400 partitions, but dynamic configuration is not supported under
- * Linux yet. An ethXX network device will be created for each
- * virtual ethernet this partition is connected to.
- *
- * - This driver is responsible for routing packets to and from other
- * partitions. The MAC addresses used by the virtual ethernets
- * contains meaning and must not be modified.
- *
- * - Having 2 virtual ethernets to the same remote partition DOES NOT
- * double the available bandwidth. The 2 devices will share the
- * available hypervisor bandwidth.
- *
- * - If you send a packet to your own mac address, it will just be
- * dropped, you won't get it on the receive side.
- *
- * - Multicast is implemented by sending the frame frame to every
- * other partition. It is the responsibility of the receiving
- * partition to filter the addresses desired.
- *
- * Tunable parameters:
- *
- * VETH_NUMBUFFERS: This compile time option defaults to 120. It
- * controls how much memory Linux will allocate per remote partition
- * it is communicating with. It can be thought of as the maximum
- * number of packets outstanding to a remote partition at a time.

+/**
+ * DOC: Virtual Function Driver Interface
+ *
+ * This file contains software structures used to form a two way
+ * communication channel between the VF driver and the PF driver,
+ * named Virtual Function Driver Interface (VFDI).
+ *
+ * For the purposes of VFDI, a page is a memory region with size and
+ * alignment of 4K. All addresses are DMA addresses to be used within
+ * the domain of the relevant VF.
+ *
+ * The only hardware-defined channels for a VF driver to communicate
+ * with the PF driver are the event mailboxes (%FR_CZ_USR_EV
+ * registers). Writing to these registers generates an event with
+ * EV_CODE = EV_CODE_USR_EV, USER_QID set to the index of the mailbox
+ * and USER_EV_REG_VALUE set to the value written. The PF driver may
+ * direct or disable delivery of these events by setting
+ * %FR_CZ_USR_EV_CFG.
+ *
+ * The PF driver can send arbitrary events to arbitrary event queues.
+ * However, for consistency, VFDI events from the PF are defined to
+ * follow the same form and be sent to the first event queue assigned
+ * to the VF while that queue is enabled by the VF driver.
+ *
+ * The general form of the variable bits of VFDI events is:
+ *
+ * 0 16 24 31
+ * | DATA | TYPE | SEQ |
+ *
+ * SEQ is a sequence number which should be incremented by 1 (modulo
+ * 256) for each event. The sequence numbers used in each direction
+ * are independent.
+ *
+ * The VF submits requests of type &struct vfdi_req by sending the
+ * address of the request (ADDR) in a series of 4 events:
+ *
+ * 0 16 24 31
+ * | ADDR[0:15] | VFDI_EV_TYPE_REQ_WORD0 | SEQ |
+ * | ADDR[16:31] | VFDI_EV_TYPE_REQ_WORD1 | SEQ+1 |
+ * | ADDR[32:47] | VFDI_EV_TYPE_REQ_WORD2 | SEQ+2 |
+ * | ADDR[48:63] | VFDI_EV_TYPE_REQ_WORD3 | SEQ+3 |
+ *
+ * The address must be page-aligned. After receiving such a valid
+ * series of events, the PF driver will attempt to read the request
+ * and write a response to the same address. In case of an invalid
+ * sequence of events or a DMA error, there will be no response.
+ *
+ * The VF driver may request that the PF driver writes status
+ * information into its domain asynchronously. After writing the
+ * status, the PF driver will send an event of the form:
+ *
+ * 0 16 24 31
+ * | reserved | VFDI_EV_TYPE_STATUS | SEQ |
+ *
+ * In case the VF must be reset for any reason, the PF driver will
+ * send an event of the form:
+ *
+ * 0 16 24 31
+ * | reserved | VFDI_EV_TYPE_RESET | SEQ |
+ *
+ * It is then the responsibility of the VF driver to request
+ * reinitialisation of its queues.

+ * This driver supports wwan (3G/LTE/?) devices using a vendor
+ * specific management protocol called Qualcomm MSM Interface (QMI) -
+ * in addition to the more common AT commands over serial interface
+ * management
+ *
+ * QMI is wrapped in CDC, using CDC encapsulated commands on the
+ * control ("master") interface of a two-interface CDC Union
+ * resembling standard CDC ECM. The devices do not use the control
+ * interface for any other CDC messages. Most likely because the
+ * management protocol is used in place of the standard CDC
+ * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
+ *
+ * Handling a protocol like QMI is out of the scope for any driver.
+ * It can be exported as a character device using the cdc-wdm driver,
+ * which will enable userspace applications ("modem managers") to
+ * handle it. This may be required to use the network interface
+ * provided by the driver.
+ *
+ * These devices may alternatively/additionally be configured using AT
+ * commands on any of the serial interfaces driven by the option driver
+ *
+ * This driver binds only to the data ("slave") interface to enable
+ * the cdc-wdm driver to bind to the control interface. It still
+ * parses the CDC functional descriptors on the control interface to
+ * a) verify that this is indeed a handled interface (CDC Union
+ * header lists it as slave)
+ * b) get MAC address and other ethernet config from the CDC Ethernet
+ * header
+ * c) enable user bind requests against the control interface, which
+ * is the common way to bind to CDC Ethernet Control Model type
+ * interfaces
+ * d) provide a hint to the user about which interface is the
+ * corresponding management interface
