      qmi_wwan: Support dynamic config on Quectel EP06 · 7c5cca35
      Kristian Evensen 提交于
      Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB
      interfaces, without the device changing VID/PID or configuration number.
      When the configuration is updated and interfaces are added/removed, the
      interface numbers change. This means that the current code for matching
      EP06 does not work.
      
      This patch removes the current EP06 interface number match, and replaces
      it with a match on class, subclass and protocol. Unfortunately, matching
      on those three alone is not enough, as the diag interface exports the
      same values as QMI. The other serial interfaces + adb export different
      values and do not match.
      
      The diag interface only has two endpoints, while the QMI interface has
      three. I have therefore added a check for number of interfaces, and we
      ignore the interface if the number of endpoints equals two.

      qmi_wwan: fix interface number for DW5821e production firmware · f25e1392
      Aleksander Morgado 提交于
      The original mapping for the DW5821e was done using a development
      version of the firmware. Confirmed with the vendor that the final
      USB layout ends up exposing the QMI control/data ports in USB
      config #1, interface #0, not in interface #1 (which is now a HID
      interface).

      qmi_wwan: do not steal interfaces from class drivers · 5697db4a
      Bjørn Mork 提交于
      The USB_DEVICE_INTERFACE_NUMBER matching macro assumes that
      the { vendorid, productid, interfacenumber } set uniquely
      identifies one specific function.  This has proven to fail
      for some configurable devices. One example is the Quectel
      EM06/EP06 where the same interface number can be either
      QMI or MBIM, without the device ID changing either.
      
      Fix by requiring the vendor-specific class for interface number
      based matching.  Functions of other classes can and should use
      class based matching instead.

      qmi_wwan: Add missing skb_reset_mac_header-call · 0de0add1
      Kristian Evensen 提交于
      When we receive a packet on a QMI device in raw IP mode, we should call
      skb_reset_mac_header() to ensure that skb->mac_header contains a valid
      offset in the packet. While it shouldn't really matter, the packets have
      no MAC header and the interface is configured as-such, it seems certain
      parts of the network stack expects a "good" value in skb->mac_header.
      
      Without the skb_reset_mac_header() call added in this patch, for example
      shaping traffic (using tc) triggers the following oops on the first
      received packet:
