TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets.
If the socket is of family AF_INET6, call ipv6_recv_error instead
of ip_recv_error.

This change is more complex than a single branch due to the loadable
ipv6 module. It reuses a pre-existing indirect function call from
ping. The ping code is safe to call, because it is part of the core
ipv6 module and always present when AF_INET6 sockets are active.

It may also be worthwhile to add WARN_ON_ONCE(sk->family == AF_INET6)
to ip_recv_error.

Some VF drivers use the upper byte of "param1" (the qp count field)
in mlx4_qp_reserve_range() to pass flags which are used to optimize
the range allocation.

Under the current code, if any of these flags are set, the 32-bit
count field yields a count greater than 2^24, which is out of range,
and this VF fails.

As these flags represent a "best-effort" allocation hint anyway, they may
safely be ignored. Therefore, the PF driver may simply mask out the bits.

====================
Fix outer UDP checksums for IPv6 VXLAN tunnels

In testing against an older kernel I found a couple issues in the IPv6
VXLAN tunnel checksum logic for the outer UDP checksum.

First the default transitioned from using an outer checksum to not using
one.  Second, sometime after that the checksum inputs were changed
resulting the checksum not being correct if it were computed.

These two issues prevented a ping from the newer kernel to the older one.
With these two changes applied I verified I was able to send traffic over
the VXLAN tunnel to a link partner on an older kernel.

The boolean flip fix can be submitted for 3.17 stable as well since the
patch that introduced the issue was included in that kernel.

Signed-off-by: David S. Miller <davem@davemloft.net>

In "vxlan: Call udp_sock_create" there was a logic error that resulted in
the default for IPv6 VXLAN tunnels going from using checksums to not using
checksums.  Since there is currently no support in iproute2 for setting
these values it means that a kernel after the change cannot talk over a IPv6
VXLAN tunnel to a kernel prior the change.

The UDP checksum calculation for VXLAN tunnels is currently using the
socket addresses instead of the actual packet source and destination
addresses.  As a result the checksum calculated is incorrect in some
cases.

Also uh->check was being set twice, first it was set to 0, and then it is
set again in udp6_set_csum.  This change removes the redundant assignment
to 0.

The issue is that test_and_set_bit() done on adapter->state is being
performed *after* the netdevice has been freed via free_netdev().

When netdev is being allocated on initialization time, it allocates
a private area, here struct ixgbe_adapter, that resides after the
net_device structure. In ixgbe_probe(), the device init routine,
we set up the adapter after alloc_etherdev_mq() on the private area
and add a reference for the pci_dev as well via pci_set_drvdata().

Both in the error path of ixgbe_probe(), but also on module unload
when ixgbe_remove() is being called, commit 41c62843 ("ixgbe:
Fix rcu warnings induced by LER") accesses adapter after free_netdev().
The patch stores the result in a bool and thus fixes above oops on my
side.

Pull ACPI power management fix from Rafael Wysocki:
 "This is just a one-liner fixing a regression introduced in 3.13 that
  broke system suspend on some Chromebooks.

  On those machines there are ACPI device objects for some I2C devices
  that can wake up the system from sleep states, but that is done via a
  platform-specific mechanism and the ACPI objects don't contain any
  wakeup-related information.  When we started to use ACPI power
  management with those devices (which happened during the 3.13 cycle),
  their configuration confused the ACPI PM layer that returned error
  codes from suspend callbacks for them causing system suspend to fail.

  However, the ACPI PM layer can safely ignore the wakeup setting from a
  device driver if the ACPI object corresponding to the device in
  question doesn't contain wakeup information in which case the driver
  itself is responsible for setting up the device for system wakeup"
