      USB: qmi_wwan: Add quirk for Quectel EC20 Mini PCIe module · b3d8cf01
      由 Petr Štetiar 提交于 
      This device has same vendor and product IDs as G2K devices, but it has
different number of interfaces(4 vs 5) and also different interface
layout where EC20 has QMI on interface 4 instead of 0.

      qmi_wwan: Set random MAC on devices with buggy fw · 531ad428
      由 Kristian Evensen 提交于 
      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.

      usbnet: remove generic hard_header_len check · eb85569f
      由 Emil Goode 提交于 
      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.

      net: qmi_wwan: add new Qualcomm devices · 0470667c
      由 Bjørn Mork 提交于 
      Adding the device list from the Windows driver description files
included with a new Qualcomm MDM9615 based device, "Alcatel-sbell
ASB TL131 TDD LTE", from China Mobile.  This device is tested
and verified to work.  The others are assumed to work based on
using the same Windows driver.

Many of these devices support multiple QMI/wwan ports, requiring
multiple interface matching entries.  All devices are composite,
providing a mix of one or more serial, storage or Android Debug
Brigde functions in addition to the wwan function.

This device list included an update of one previously known device,
which was incorrectly assumed to have a Gobi 2K layout.  This is
corrected.

      drivers/net: Convert uses of compare_ether_addr to ether_addr_equal · 7367d0b5

      Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.
