====================
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.

      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.

- Fix GSO constants to match NETIF flags
- Fix logic in saving checksum complete in __skb_checksum_complete
- Call __skb_checksum_complete from UDP if we are checksumming over
  whole packet in order to save checksum.
- Fixes to VXLAN to work correctly with checksum complete

      net: add skb_pop_rcv_encapsulation · e5eb4e30
      Tom Herbert authored 
      This function is used by UDP encapsulation protocols in RX when
crossing encapsulation boundary. If ip_summed is set to
CHECKSUM_UNNECESSARY and encapsulation is not set, change to
CHECKSUM_NONE since the checksum has not been validated within the
encapsulation. Clears csum_valid by the same rationale.
