      sfc: ethtool: Refactor to remove fallthrough comments in case blocks · c7449b75
      Joe Perches authored
      Converting fallthrough comments to fallthrough; creates warnings
      in this code when compiled with gcc.
      
      This code is overly complicated and reads rather better with a
      little refactoring and no fallthrough uses at all.
      
      Remove the fallthrough comments and simplify the written source
      code while reducing the object code size.
      
      Consolidate duplicated switch/case blocks for IPV4 and IPV6.

      This reverts commit 4cda7527
      from net-next.
      
      Brown bag time.
      
      Michal noticed that this change doesn't work at all when
      netif_set_real_num_tx_queues() gets called prior to an initial
      dev_activate(), as for instance igb does.
      
      Doing so dies with:

      Alex Elder authored
      The definitions for the "qcom,smem-states" and "qcom,smem-state-names"
      properties need to list their "$ref" under an "allOf" keyword.
      
      In addition, fix two problems in the example at the end:
        - Use #include for header files that define needed symbolic values
        - Terminate the line that includes the "ipa-shared" register space
          name with a comma rather than a semicolon
      
      Finally, update some white space in the example for better alignment.

      net: sched: make newly activated qdiscs visible · 4cda7527
      Julian Wiedmann authored
      In their .attach callback, mq[prio] only add the qdiscs of the currently
      active TX queues to the device's qdisc hash list.
      If a user later increases the number of active TX queues, their qdiscs
      are not visible via eg. 'tc qdisc show'.
      
      Add a hook to netif_set_real_num_tx_queues() that walks all active
      TX queues and adds those which are missing to the hash list.

      cdc_ncm: Implement the 32-bit version of NCM Transfer Block · 0fa81b30
      Alexander Bersenev authored
      The NCM specification defines two formats of transfer blocks: with 16-bit
      fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is
      implemented.
      
      This patch adds the support of NTB-32. The motivation behind this is that
      some devices such as E5785 or E5885 from the current generation of Huawei
      LTE routers do not support NTB-16. The previous generations of Huawei
      devices are also use NTB-32 by default.
      
      Also this patch enables NTB-32 by default for Huawei devices.
      
      During the 2019 ValdikSS made five attempts to contact Huawei to add the
      NTB-16 support to their router firmware, but they were unsuccessful.
