2015-11-02qmi_wwan: fix entry for HP lt4112 LTE/HSPA+ Gobi 4G ModuleBjørn Mork
The lt4112 is a HP branded Huawei me906e modem. Like other Huawei modems, it does not have a fixed interface to function mapping. Instead it uses a Huawei specific scheme: functions are mapped by subclass and protocol. However, the HP vendor ID is used for modems from many different manufacturers using different schemes, so we cannot apply a generic vendor rule like we do for the Huawei vendor ID. Replace the previous lt4112 entry pointing to an arbitrary interface number with a device specific subclass + protocol match.

2015-01-02qmi_wwan: Set random MAC on devices with buggy fwKristian Evensen
Some buggy firmwares export an incorrect MAC address (00:a0:c6:00:00:00). This makes for example checking devices for random MAC addresses tricky, and you might end up with multiple network interfaces with the same address. This patch tries to fix, or at least improve, the situation by setting the MAC address of devices with this firmware bug to a random address. I tested the patch with two devices that has this firmware bug (Huawei E398 and E392), and network traffic worked fine after changing the address.

2014-02-17usbnet: remove generic hard_header_len checkEmil Goode
This patch removes a generic hard_header_len check from the usbnet module that is causing dropped packages under certain circumstances for devices that send rx packets that cross urb boundaries. One example is the AX88772B which occasionally send rx packets that cross urb boundaries where the remaining partial packet is sent with no hardware header. When the buffer with a partial packet is of less number of octets than the value of hard_header_len the buffer is discarded by the usbnet module. With AX88772B this can be reproduced by using ping with a packet size between 1965-1976. The bug has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=29082 This patch introduces the following changes: - Removes the generic hard_header_len check in the rx_complete function in the usbnet module. - Introduces a ETH_HLEN check for skbs that are not cloned from within a rx_fixup callback. - For safety a hard_header_len check is added to each rx_fixup callback function that could be affected by this change. These extra checks could possibly be removed by someone who has the hardware to test. - Removes a call to dev_kfree_skb_any() and instead utilizes the dev->done list to queue skbs for cleanup. The changes place full responsibility on the rx_fixup callback functions that clone skbs to only pass valid skbs to the usbnet_skb_return function.

2013-06-11qmi_wwan/cdc_ether: let qmi_wwan handle the Huawei E1820Bjørn Mork
Another QMI speaking Qualcomm based device, which should be driven by qmi_wwan, while cdc_ether should ignore it. Like on other Huawei devices, the wwan function can appear either as a single vendor specific interface or as a CDC ECM class function using separate control and data interfaces. The ECM control interface protocol is 0xff, likely in an attempt to indicate that vendor specific management is required. In addition to the near standard CDC class, Huawei also add vendor specific AT management commands to their firmwares. This is probably an attempt to support non-Windows systems using standard class drivers. Unfortunately, this part of the firmware is often buggy. Linux is much better off using whatever native vendor specific management protocol the device offers, and Windows uses, whenever possible. This means QMI in the case of Qualcomm based devices. The E1820 has been verified to work fine with QMI. Matching on interface number is necessary to distiguish the wwan function from serial functions in the single interface mode, as both function types will have class/subclass/function set to ff/ff/ff. The control interface number does not change in CDC ECM mode, so the interface number matching rule is sufficient to handle both modes. The cdc_ether blacklist entry is only relevant in CDC ECM mode, but using a similar interface number based rule helps document this as a transfer from one driver to another. Other Huawei 02/06/ff devices are left with the cdc_ether driver because we do not know whether they are based on Qualcomm chips. The Huawei specific AT command management is known to be somewhat hardware independent, and their usage of these class codes may also be independent of the modem hardware.
