      netxen: free napi resources during detach · 232e7d68
      Dhananjay Phadke authored
      
      
      o Defer napi resouce allocation to device attach.
      
      o Free napi resources and delete napi during detach.
      
      This ensures right behavior across firmware reset.

      netxen: remove netxen workqueue · e424fa9d
      Amit Kumar Salecha authored
      
      
      o Remove private workqueue in the driver, move all
        scheduled tasks to keventd workqueues. This makes
        ports (interfaces) of same / different NIC boards
        independent, in terms of their link watchdog and
        reset tasks.
      
      o Move quick checks for link status and temperature
        in timer callback, schedule watchdog task only if
        link status changed or temperature reached critical
        threshold.
      
      This also fixes deadlock when thermal panic occurs,
      watchdog work was flushing workqueue that it was
      sitting on.

      ixgbe: fix issues setting rx-usecs with legacy interrupts · 237057ad
      Don Skidmore authored
      
      
      Currently setting rx-usecs when the interface is in legacy interrupt
      mode it is not immediate.  We were only setting EITR for each MSIx
      vector and since this count would be zero for legacy mode it wasn't
      set until after a reset.  This patch corrects that by checking what
      mode we are in and then setting EITR accordingly.

      can: fix oops caused by wrong rtnl newlink usage · 993e6f2f
      Oliver Hartkopp authored
      For 'real' hardware CAN devices the netlink interface is used to set CAN
      specific communication parameters. Real CAN hardware can not be created with
      the ip tool ...
      
      The invocation of 'ip link add type can' lead to an oops as the standard rtnl
      newlink function was called:
      
      http://bugzilla.kernel.org/show_bug.cgi?id=13954
      
      
      
      This patch adds a private newlink function for the CAN device driver interface
      that unconditionally returns -EOPNOTSUPP.

      mac80211: fix panic when splicing unprepared TIDs · 416fbdff
      Luis R. Rodriguez authored
      We splice skbs from the pending queue for a TID
      onto the local pending queue when tearing down a
      block ack request. This is not necessary unless we
      actually have received a request to start a block ack
      request (rate control, for example). If we never received
      that request we should not be splicing the tid pending
      queue as it would be null, causing a panic.
      
      Not sure yet how exactly we allowed through a call when the
      tid state does not have at least HT_ADDBA_REQUESTED_MSK set,
      that will require some further review as it is not quite
      obvious.
      
      For more information see the bug report:
      
      http://bugzilla.kernel.org/show_bug.cgi?id=13922
      
      
      
      This fixes this oops:
