      ====================
      Intel Wired LAN Driver Updates 2014-06-20
      
      This series contains updates to i40e and i40evf.
      
      Anjali provides an update to the registers to handle the updates from the
      hardware.  Also provides a fix so that we do not try to access the rings
      through the qvectors at the time of freeing the qvectors.
      
      Jesse provides a workaround for some older NVM versions where the NVM
      was not filling in the GLQF_HKEY register, so made sure that the
      critical register is initialized.
      
      Michal provides a fix to reset the head and tail on admin queue
      initialization where head and tail are not reset by the hardware.
      
      Neerav adds a helper routine that would wait for the Rx/Tx queue to reach
      the enable or disable state that is requested.  Also provides a fix
      to the debugfs command "lldp get remote" which was dumping the local
      LLDPDU instead of the peer's LLDPDU.  Fixed a bug when all the Tx hang
      recovery mechanisms have failed and the driver tries to bring down the
      interface in the interrupt context.
      
      Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats
      when the PF stats are cleared.  Also cleans the service tasks so that
      they do not run while a reset is in progress.
      
      Mitch fixes an issue in i40evf_get_rxfh() where only fifteen registers
      were being read instead of all sixteen.
      
      Carolyn provides a change to the RSS configuration to set table size and
      write to the hardware to confirm the RSS table size being used.
      
      Kamil makes a change to the admin queue debug prints so that they will not
      cause segmentation faults in some of our tool applications.

      Pull NVMe update from Matthew Wilcox:
       "Mostly bugfixes again for the NVMe driver.  I'd like to call out the

        We've had a few reports from people who're really pounding on NVMe
        devices at scale, hence the timeout changes (and new module
        parameters), hotplug cpu deadlock, tracepoints, and minor performance
        tweaks"

      net: sctp: fix permissions for rto_alpha and rto_beta knobs · b58537a1
      Daniel Borkmann authored
      Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs
      to jiffies conversions.") has silently changed permissions for
      rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of
      this was to discourage users from tweaking rto_alpha and
      rto_beta knobs in production environments since they are key
      to correctly compute rtt/srtt.
      
      RFC4960 under section 6.3.1. RTO Calculation says regarding
      rto_alpha and rto_beta under rule C3 and C4:
      
        [...]
        C3)  When a new RTT measurement R' is made, set
      
             RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'|
      
             and
      
             SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R'
      
             Note: The value of SRTT used in the update to RTTVAR
             is its value before updating SRTT itself using the
             second assignment. After the computation, update
             RTO <- SRTT + 4 * RTTVAR.
      
        C4)  When data is in flight and when allowed by rule C5
             below, a new RTT measurement MUST be made each round
             trip. Furthermore, new RTT measurements SHOULD be
             made no more than once per round trip for a given
             destination transport address. There are two reasons
             for this recommendation: First, it appears that
             measuring more frequently often does not in practice
             yield any significant benefit [ALLMAN99]; second,
             if measurements are made more often, then the values
             of RTO.Alpha and RTO.Beta in rule C3 above should be
             adjusted so that SRTT and RTTVAR still adjust to
             changes at roughly the same rate (in terms of how many
             round trips it takes them to reflect new values) as
             they would if making only one measurement per
             round-trip and using RTO.Alpha and RTO.Beta as given
             in rule C3. However, the exact nature of these
             adjustments remains a research issue.
        [...]
      
      While it is discouraged to adjust rto_alpha and rto_beta
      and not further specified how to adjust them, the RFC also
      doesn't explicitly forbid it, but rather gives a RECOMMENDED
      default value (rto_alpha=3, rto_beta=2). We have a couple
      of users relying on the old permissions before they got
      changed. That said, if someone really has the urge to adjust
      them, we could allow it with a warning in the log.
