  • 269f8cb26   net: fix USB network driver config option. ... Browse Code »

    It must be tristate to avoid broken dependencies with kernel built-in
    usb network drivers when usb support is module only.

    When net config option is set, least surprize default should match usb.

    Wireless RNDIS USB driver used to select USB_USBNET. USB_USBNET now
    depends on USB_NET_DRIVERS so the latter should be selected as well.

    USB network drivers are already handled in drivers/net/usb/Kconfig.
    Let's save the maintenance burden of dependencies in drivers/net/Makefile.

    The newly introduced USB_NET_DRIVERS umbrella config option defaults
    to 'y' so as to minimize the changes of behavior.

    All drivers that select MII also need to select NET_CORE because MII
    depends on it. This is a bit ridiculous because NET_CORE is just a
    menu option that doesn't enable any code by itself.

    There is also no need for it to be a visible option, since its users
    all select it.

  • e2ca90c27   ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver ... Browse Code »

    This is a resubmission.
    Added kfree() in ax88179_get_eeprom to prevent memory leakage.
    Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
    Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
    Fixed endianness issue on big endian systems and verified this driver on iBook G4.
    Removed steps that change net->features in ax88179_set_features function.
    Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
    Fixed the issue that the default MTU is not 1500.
    Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
    MTU higher than 1500.
    Fixed indentation and empty line coding style errors.
    The _nopm version usb functions were added to access register in suspend and resume functions.
    Serveral variables allocted dynamically were removed and replaced by stack variables.
    ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.

    This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
    to gigabit ethernet adapters. It's based on the AX88xxx driver but
    the usb commands used to access registers for AX88179 are completely different.
    This driver had been verified on x86 system with AX88179/AX88178A and
    Sitcomm LN-032 USB dongles.

  • 4f73bc4dd   tty: Added a CONFIG_TTY option to allow removal of TTY ... Browse Code »

    The option allows you to remove TTY and compile without errors. This
    saves space on systems that won't support TTY interfaces anyway.
    bloat-o-meter output is below.

    The bulk of this patch consists of Kconfig changes adding "depends on
    TTY" to various serial devices and similar drivers that require the TTY
    layer. Ideally, these dependencies would occur on a common intermediate
    symbol such as SERIO, but most drivers "select SERIO" rather than
    "depends on SERIO", and "select" does not respect dependencies.

    bloat-o-meter output comparing our previous minimal to new minimal by
    removing TTY. The list is filtered to not show removed entries with awk
    '$3 != "-"' as the list was very long.

  • 9b28ecd66   net: usb: qmi_wwan: New driver for Huawei QMI based WWAN devices ... Browse Code »

    Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
    near standard CDC ECM interfaces in addition to the usual serial
    interfaces. The Huawei E392/E398 are examples of such devices.

    These typically cannot be fully configured using AT commands
    over a serial interface. It is necessary to speak the proprietary
    Qualcomm MSM Interface (QMI) protocol to the device to enable the
    ethernet proxy functionality.

    The devices embed the QMI protocol in CDC on the control interface,
    using standard CDC commands and notifications. The do not otherwise
    use CDC commands for the ethernet function. This driver does
    therefore not need access to any other aspects of the control
    interface than the descriptors attached to it.

    Another driver, cdc-wdm, will provide userspace access to the
    QMI protocol independently of this driver. To facilitate this,
    this driver avoids binding to the control interface, and uses
    only the associated data interface after parsing the common CDC
    functional descriptors on the control interface.

    You will want both the cdc-wdm and option drivers as companions to
    this driver, to have full access to all interfaces and protocols
    exported by the device.

  • d40261236   net/usb: Add Samsung Kalmia driver for Samsung GT-B3730 ... Browse Code »

    Introducing driver for the network port of Samsung Kalmia based USB LTE modems.
    It has also an ACM interface that previous patches associates with the "option"
    module. To access those interfaces, the modem must first be switched from modem
    mode using a tool like usb_modeswitch.

    As the proprietary protocol has been discovered by watching the MS Windows driver
    behavior, there might be errors in the protocol handling, but stable and fast
    connection has been established for hours with Norwegian operator NetCom that
    distributes this modem with their LTE/4G subscription.

    More and updated information about how to use this driver is available here:

  • 7a635ea98   net/usb: Ethernet quirks for the LG-VL600 4G modem ... Browse Code »

    This adds a driver for the CDC Ethernet part of this modem. The
    device's ID is blacklisted in cdc_ether.c and is white-listed in
    this new driver because of the quirks needed to make it useful.
    The modem's firmware exposes a CDC ACM port for modem control and a
    CDC Ethernet port for network data. The descriptors look fine but
    both ports actually are some sort of multiplexers requiring non-
    standard headers added/removed from every packet or they get
    ignored. All information is based on a usb traffic log from a
    Windows machine.

    On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
    this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.
    Userspace scripts are required to talk to the CDC ACM port.

  • cc28a20e7   introduce cx82310_eth: Conexant CX82310-based ADSL router USB ethernet driver ... Browse Code »

    This patch introduces cx82310_eth driver - driver for USB ethernet port of
    ADSL routers based on Conexant CX82310 chips. Such routers usually have
    ethernet port(s) too which are bridged together with the USB ethernet port,
    allowing the USB-connected machine to communicate to the network (and also
    internet through the ADSL, of course).

    This is my first driver, so please check thoroughly. As there's no protocol
    documentation, it was done with usbsnoop dumps from Windows driver, some
    parts (the commands) inspired by cxacru driver and also other usbnet drivers.
    The driver passed my testing - some real work and also pings sized from 0 to
    65507 B.

    The only problem I found is the ifconfig error counter. When I return 0 (or 1
    but empty skb) from rx_fixup(), usbnet increases the error counter although
    it's not an error condition (because packets can cross URB boundaries). Maybe
    the usbnet should be fixed to allow rx_fixup() to return empty skbs (or some
    other value, e.g. 2)?

    The USB ID of my device is 0x0572:0xcb01 which conflicts with some ADSL modems
    using cxacru driver (they probably use the same chipset but simpler
    firmware). The modems seem to use bDeviceClass 0 and iProduct "ADSL USB
    MODEM", my router uses bDeviceClass 255 and iProduct "USB NET CARD". The
    driver matches only devices with class 255 and checks for the iProduct string
    during init. I already posted a patch for the cxacru driver to ignore these
    devices.

  • eb4fd8cd3   net/usb: add sierra_net.c driver ... Browse Code »

    Re-submitted based on comments from netdev community.
    Summary of the changes:
    1. Improved error handling.
    2. Added the missing timeout arguments to usb_control_msg().

    The following is a new Linux driver which exposes certain models of Sierra
    Wireless modems to the operating system as Network Interface Cards (NICs).

    This driver requires a version of the sierra.c driver which supports
    blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
    claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
    (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
    The version of sierra.c which supports blacklisting is
    available from the sierra wireless knowledge base page for older kernels. It is
    also available in Linux kernel starting from version 2.6.31.

    This driver works with all Sierra Wireless devices configured with PID=68A3
    like USB305, USB306 provided the corresponding firmware version is I2.0
    (for USB305) or M3.0 (for USB306) and later.
    This driver will not work with earlier firmware versions than the ones shown
    above. In this case the driver will issue an error message indicating
    incompatibility and will not serve the device's USB-to-WWAN interface.

    Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
    A series of hook functions are provided in sierra_net.c which are called by
    usbnet.c in response to a particular condition such as receipt or transmission
    of a data packet. As such, usbnet.c does most of the work of making
    a modem appear to the system as a network device and for properly exchanging
    traffic between the USB subsystem and the Network card interface.
    Sierra_net.c is concerned with managing the data exchanged between the
    USB-to-WWAN interface and the upper layers of the operating system.

    EEM is different from the Ethernet Control Model (ECM) currently

    that it doesn't require of USB interface alternate settings to
    manage interface state; some maldesigned hardware can't handle
    that part of USB. It also avoids a separate USB interface for
    control and status updates.
