Instead of using directly the OS timer through direct register access,
use the standard sched_clock(), which will end up in OSCR reading
anyway.
This is a first step for direct access register removal and machine
specific code removal from this driver.
This commit changes the behavior, as previously the minimum turnaround
time was counted in 76ns steps, while with this patch it is counted in
microsecond steps. The strictly equal formula would have been :

In the new flow, we separate the pci initialization and teardown from the
initialization and teardown of the other resources.
init_one calls mlx5_pci_init that handles the pci resources initialization.
It then calls mlx5_load_one to initialize the remainder of the resources.
When removing a device, remove_one is invoked. However, now remove_one
calls mlx5_unload_one to free all the resources except the pci resources.
When mlx5_unload_one returns, mlx5_pci_close is called to free the pci
resources.
The above separation will allow us to implement the pci error handlers and
suspend and resume callbacks.

We found that a TCP Fast Open passive connection was vulnerable
to reorders, as the exchange might look like
[1] C -> S S <FO ...> <request>
[2] S -> C S. ack request <options>
[3] S -> C . <answer>
packets [2] and [3] can be generated at almost the same time.
If C receives the 3rd packet before the 2nd, it will drop it as
the socket is in SYN_SENT state and expects a SYNACK.
S will have to retransmit the answer.
Current OOO avoidance in linux is defeated because SYNACK
packets are attached to the LISTEN socket, while DATA packets
are attached to the children. They might be sent by different cpus,
and different TX queues might be selected.
It turns out that for TFO, we created a child, which is a
full blown socket in TCP_SYN_RECV state, and we simply can attach
the SYNACK packet to this socket.
This means that at the time tcp_sendmsg() pushes DATA packet,
skb->ooo_okay will be set iff the SYNACK packet had been sent
and TX completed.
This removes the reorder source at the host level.
We also removed the export of tcp_try_fastopen(), as it is no
longer called from IPv6.

Intel Wired LAN Driver Updates 2015-09-28
This series contains updates to i40e, i40evf and igb to resolve issues
seen and reported by Red Hat.
Kiran moves i40e_get_head() in preparation for the refactor of the Tx
timeout logic, so that it can be used in other areas of the driver.
Refactored the driver timeout logic by issuing a writeback request via
a software interrupt to the hardware the first time the driver detects
a hang. This was due to the driver being too aggressive in resetting a
hung queue.
Shannon adds the GRE protocol to the transmit checksum encoding.
Anjali fixes an issue of forcing writeback too often, which caused us to
not benefit from NAPI. We now disable force writeback in the clean
routine for X710 and XL710 adapters. The X722 adapters do not enable
interrupt to force a writeback and benefit from WB_ON_ITR and so force
WB is left enabled for those adapters. Fixed a possible deadlock issue
where sync_vsi_filters() can be called directly under RTNL or through
the timer subtask without RTNL. So update the flow to see if we are
already under RTNL before trying to grab it.
Stefan Assmann provides a fix for igb where SR-IOV was not getting
enabled properly and we ran into a NULL pointer if the max_vfs module
parameter is specified. This is prevented by setting the
IGB_FLAG_HAS_MSIX bit before calling igb_probe_vfs().
v2: added "i40e: Fix for recursive RTNL lock during PROMISC change" patch
to the series, as it resolves another issues seen and reported by
Red Hat.

In igb_sw_init() the sequence of calls was changed from
igb_init_queue_configuration()
igb_init_interrupt_scheme()
igb_probe_vfs()
to
igb_probe_vfs()
igb_init_queue_configuration()
igb_init_interrupt_scheme()
This results in adapter->flags not having the IGB_FLAG_HAS_MSIX bit set
during igb_probe_vfs()->igb_enable_sriov(). Therefore SR-IOV does not
get enabled properly and we run into a NULL pointer if the max_vfs
module parameter is specified (adapter->vf_data does not get allocated,
crash on accessing the structure).

The sync_vsi_filters function can be called directly under RTNL
or through the timer subtask without one. This was causing a deadlock.
If sync_vsi_filters is called from a thread which held the lock,
and in another thread the PROMISC setting got changed we would
be executing the PROMISC change in the thread which already held
the lock alongside the other filter update. The PROMISC change
requires a reset if we are on a VEB, which requires it to be called
under RTNL.
Earlier the driver would call reset for PROMISC change without
checking if we were already under RTNL and would try to grab it
causing a deadlock. This patch changes the flow to see if we are
already under RTNL before trying to grab it.

This patch fixes the issue of forcing WB too often causing us to not

Without this patch we were forcing WB/arming interrupt too often taking

With this patch we disable force WB in the clean routine for X710
and XL710 adapters. X722 adapters do not enable interrupt to force
a WB and benefit from WB_ON_ITR and hence force WB is left enabled
for those adapters.
For XL710 and X710 adapters if we have less than 4 packets pending
a software Interrupt triggered from service task will force a WB.
This patch also changes the conditions for setting RS bit as described
in code comments. This optimizes when the HW does a tail bump and when
it does a WB. It also optimizes when we do a wmb.

vxlan: support both IPv4 and IPv6 sockets
Note: this needs net merged into net-next in order to apply.
It's currently not easy enough to work with metadata based vxlan tunnels. In
particular, it's necessary to create separate network interfaces for IPv4
and IPv6 tunneling. Assigning an IPv6 address to an IPv4 interface is
allowed yet won't do what's expected. With route based tunneling, one has to
pay attention to use the vxlan interface opened with the correct family.
Other users of this (openvswitch) would need to always create two vxlan
interfaces.
Furthermore, there's no sane API for creating an IPv6 vxlan metadata based
interface.
This patchset simplifies this by opening both IPv4 and IPv6 socket if the
vxlan interface has the metadata flag (IFLA_VXLAN_COLLECT_METADATA) set.
Assignment of addresses etc. works as expected after this.

Provide a .ndo_features_check() method which drops the NETIF_F_TSO

Then we can stop the masking in cp_start_xmit(), and just WARN if the
