      ====================
      Amitkumar Karwar gives us two mwifiex fixes: one fixes some skb
      manipulations when handling some event messages; and another that
      does some similar fixing on an error path.
      
      Avinash Patil gives us a fix for for a memory leak in mwifiex.
      
      Dan Rosenberg offers an NFC NCI fix to enforce some message length
      limits to prevent buffer overflows.
      
      Eliad Peller provides a mac80211 fix to prevent some frames from
      being built with an invalid BSSID.
      
      Eric Dumazet sends an NFC fix to prevent a BUG caused by a NULL
      pointer dereference.
      
      Felix Fietkau has an ath9k fix for a regression causing
      LEAP-authenticated connection failures.
      
      Johannes Berg provides an iwlwifi fix that eliminates some log SPAM
      after an authentication/association timeout.  He also provides a
      mac80211 fix to prevent incorrectly addressing certain action frames
      (and in so doing, to comply with the 802.11 specs).
      
      Larry Finger provides a few USB IDs for the rtl8192cu driver --
      should be harmless.
      
      Panayiotis Karabassis provices a one-liner to fix kernel bug 42903
      (a system freeze).
      
      Randy Dunlap provides a one-line Kconfig change to prevent build
      failures with some configurations.
      
      Stone Piao provides an mwifiex sequence numbering fix and a fix
      to prevent mwifiex from attempting to include eapol frames in an
      aggregation frame.
      
      Finally, Tom Hughes provides an ath9k fix for a NULL pointer
      dereference.

      gianfar: Fix RXICr/TXICr programming for multi-queue mode · 9740e001
      Claudiu Manoil authored
      The correct behavior is to program the interrupt coalescing regs
      (RXICr/TXICr) in accordance with the Rx/Tx Q's "rx/txcoalescing"
      flag. That is, if the coalescing flag is 0 for a given Rx/Tx queue
      then the corresponding coalescing register should be cleared.
      This behavior is correctly implemented for the single-queue mode
      (SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE).
      This fixes the later case.

      net: qmi_wwan: fix Oops while disconnecting · d9b87068
      Bjørn Mork authored
      usbnet_disconnect() will set intfdata to NULL before calling
      the minidriver unbind function.  The cdc_wdm subdriver cannot
      know that it is disconnecting until the qmi_wwan unbind
      function has called its disconnect function.  This means that
      we must be able to support the cdc_wdm subdriver operating
      normally while usbnet_disconnect() is running, and in
      particular that intfdata may be NULL.
      
      The only place this matters is in qmi_wwan_cdc_wdm_manage_power
      which is called from cdc_wdm.  Simply testing for NULL
      intfdata there is sufficient to allow it to continue working
      at all times.
      
      Fixes this Oops where a cdc-wdm device was closed while the
      USB device was disconnecting, causing wdm_release to call
      qmi_wwan_cdc_wdm_manage_power after intfdata was set to
      NULL by usbnet_disconnect:
