4a97df0bfa ixgbe: fix poll loop for FDIRCTRL.INIT_DONE bit
The loop in ixgbe_reinit_fdir_tables_82599() only polls for up to 100us
resulting in failures to update the FDIR filter table at 1Gbps and 10Gbps
when under load.

The poll times for FDIRCTRL.INIT_DONE are 55us, 550us and 5.5ms for 10Gbps,
1Gbps and 100Mbps respectively.

This patch sets the wait time to be the same as in ixgbe_fdir_enable_82599()

1cc92eb871 ixgbe: fix PTP ethtool timestamping function
This patch fixes a development issue that occurred due to invalid modes reported
in the ethtool get_ts_info function. The issue is resolved by removing
unsupported modes from the Rx supported list.

8208367371 ixgbe: Fix PTP X540 SDP alignment code for PPS signal
This patch fixes a bug in the method used for calculating the trigger
alignment for SDP0 when enabling a PPS output on the X540. The alignment math
wasn't properly taking into account the overflow cyclecounter, and was
misaligning the pin triggers so that two X540 devices synced properly had
mis-aligned SDP pins. This patch fixes the math to calculate the correct
seconds alignment for the PPS signal.

da1586461e pch_gbe: Fix PTP dependencies.
The config combination:

        CONFIG_PCH_GBE=y
        CONFIG_PCH_PTP=y
        CONFIG_PTP_1588_CLOCK=m

doesn't work, because then you have a built-in kernel
object (the PCH_PTP code) referring to symbols in a
module (PTP_1588_CLOCK).

Fix this like IXGBE, by using "select PTP_1588_CLOCK"
instead of a "depends on".

This merge also removes a new use of __cancel_delayed_work(), and
replaces it with the regular cancel_delayed_work() that is now irq-safe
thanks to the workqueue updates.

That said, I suspect the sequence in question should probably use
"mod_delayed_work()".  I just did the minimal "don't use deprecated
functions" fixup, though.

 2) Make SCTP more network namespace aware, from Eric Biederman.

 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

Pull workqueue changes from Tejun Heo:
 "This is workqueue updates for v3.7-rc1.  A lot of activities this
  round including considerable API and behavior cleanups.

   * delayed_work combines a timer and a work item.  The handling of the
     timer part has always been a bit clunky leading to confusing
     cancelation API with weird corner-case behaviors.  delayed_work is
     updated to use new IRQ safe timer and cancelation now works as
     expected.

   * Another deficiency of delayed_work was lack of the counterpart of
     mod_timer() which led to cancel+queue combinations or open-coded
     timer+work usages.  mod_delayed_work[_on]() are added.

     These two delayed_work changes make delayed_work provide interface
     and behave like timer which is executed with process context.

   * A work item could be executed concurrently on multiple CPUs, which
     is rather unintuitive and made flush_work() behavior confusing and
     half-broken under certain circumstances.  This problem doesn't
     exist for non-reentrant workqueues.  While non-reentrancy check
     isn't free, the overhead is incurred only when a work item bounces
     across different CPUs and even in simulated pathological scenario
     the overhead isn't too high.

     All workqueues are made non-reentrant.  This removes the
     distinction between flush_[delayed_]work() and
     flush_[delayed_]_work_sync().  The former is now as strong as the
     latter and the specified work item is guaranteed to have finished
     execution of any previous queueing on return.

   * In addition to the various bug fixes, Lai redid and simplified CPU
     hotplug handling significantly.

   * Joonsoo introduced system_highpri_wq and used it during CPU
     hotplug.

  There are two merge commits - one to pull in IRQ safe timer from
  tip/timers/core and the other to pull in CPU hotplug fixes from
  wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.

Tejun pointed out a few of them, I fixed a couple more.

9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

Some bug fixes that should go into 3.7:

1. Fix oops when removing device with SR-IOV enabled.  (This regression
was introduced by the last set of changes, so the fix does not need to
be applied to any earlier kernel versions.)
2. Fix firmware structure field lookup bug that resulted in missing
sensor information.
3. Fix bug that makes self-test do very little in some configurations.
4. Fix the numbering of ethtool RX flow steering filters to reflect the
real hardware priorities.

 - A number of cleanup series for OMAP, moving and removing some

 - Final removal of all non-DT boards for Tegra, it is now
   device-tree-only!
 - Removal of a stale platform, nxp4008. It's an old mobile chipset
   that is no longer in use, and was very likely never really used with
   a mainline kernel. We have not been able to find anyone interested
   in keeping it around in the kernel.
 - Removal of the legacy dmaengine driver on tegra
 
 + A handful of other things that I haven't described above.

   - Removal of a stale platform, nxp4008.  It's an old mobile chipset
     that is no longer in use, and was very likely never really used
     with a mainline kernel.  We have not been able to find anyone
     interested in keeping it around in the kernel.

6ac7ef1487 sfc: Fix the reported priorities of different filter types
Each RX filter table contains filters with two different levels of
specificity: TCP/IPv4 and UDP/IPv4 filters match the local address and
port and optionally the remote address and port; Ethernet filters
match the local address and optionally the VID.  The more specific
filters always override less specific filters within the same table,
and should be numbered accordingly.

726ba0e14a sfc: Fix null function pointer in efx_sriov_channel_type
Commit c31e5f9 ('sfc: Add channel specific receive_skb handler and
post_remove callback') added the function pointer field
efx_channel_type::post_remove and an unconditional call through it.

This field should have been initialised to efx_channel_dummy_op_void
in the existing instances of efx_channel_type, but this was only done
in efx_default_channel_type.  Consequently, if a device has SR-IOV
enabled then removing the driver or device will result in an oops.

de0a41484c tg3: unconditionally select HWMON support when tg3 is enabled.
There is the seldom used corner case where HWMON=m at the same
time as TIGON3=y (typically randconfigs) which will cause a link
fail like:

drivers/built-in.o: In function `tg3_close':
tg3.c:(.text+0x16bd86): undefined reference to `hwmon_device_unregister'
drivers/built-in.o: In function `tg3_hwmon_open':
tg3.c:(.text+0x16fc4b): undefined reference to `hwmon_device_register'
make[1]: *** [vmlinux] Error 1

Fix it as suggested by DaveM[1] by having the Kconfig logic simply
select HWMON when TIGON3 is selected.  This gets rid of all the
extra IS_ENABLED ifdeffery in tg3.c as a side benefit.

96bed4b954 bnx2x,cnic: use FW 7.8.2
This patch moves the bnx2x and cnic drivers into using FW 7.8.2
which was recently submitted into the linux-firmware tree.

A short summary of minor bugs fixed by this FW:
 1. In switch dependent mode, fix several issues regarding inner vlan
    vs. DCB priorities.
 2. iSCSI - not all packets were completed on a forward channel.
 3. DCB - fixed for 4-port devices.
 4. Fixed false parity reported in CAM memories when operating near -5%
    on the 1.0V core supply.
 5. ETS default settings are set to fairness between traffic classes
    (rather than strict priority), and uses the same chip receive buffer
    configuration for both PFC and pause.

For a complete list of fixes made by this FW, see commit 236367db
in the linux-firmware git repository.

aadf4f3f66 mlx4_core: Disable SENSE_PORT for multifunction devices
In the current driver, the SENSE_PORT firmware command is issued as a
"wrapped" command, but the command handling code doesn't have a
wrapper, so it will never do anything other than log an error message.
The latest ConnectX-3 2.11.500 firmware reports the SENSE_PORT
capability even in multi-function (SR-IOV) mode, so the driver will
try to issue the command.

At least until the driver has a proper wrapper for SENSE_PORT, make
sure we disable the command for multi-function devices.

ca3e57a599 mlx4_core: Clean up enabling of SENSE_PORT for older (ConnectX-1/-2) HCAs
Instead of having a hard-coded "PCI device ID != 0x1003" (which
obviously breaks as newer devices with ID != 0x1003 become available),
instead let's set a flag in our PCI device table for the older devices
where we're supposed to force using SENSE_PORT.  This also avoids
enabling SENSE_PORT for virtual functions by mistake.

f3d4c89ee4 mlx4_core: Fix crash on uninitialized priv->cmd.slave_sem
On an SR-IOV master device, __mlx4_init_one() calls mlx4_init_hca()
before mlx4_multi_func_init().  However, for unlucky configurations,
mlx4_init_hca() might call mlx4_SENSE_PORT() (via mlx4_dev_cap()), and
that calls mlx4_cmd_imm() with MLX4_CMD_WRAPPED set.

However, on a multifunction device with MLX4_CMD_WRAPPED, __mlx4_cmd()
calls into mlx4_slave_cmd(), and that immediately tries to do

	down(&priv->cmd.slave_sem);

but priv->cmd.slave_sem isn't initialized until mlx4_multi_func_init()
(which we haven't called yet).  The next thing it tries to do is access
priv->mfunc.vhcr, but that hasn't been allocated yet.

Fix this by moving the initialization of slave_sem and vhcr up into
mlx4_cmd_init(). Also, since slave_sem is really just being used as a
mutex, convert it into a slave_cmd_mutex.

47605df953 mlx4: Modify proxy/tunnel QP mechanism so that guests do no calculations
Previously, the structure of a guest's proxy QPs followed the
structure of the PPF special qps (qp0 port 1, qp0 port 2, qp1 port 1,
qp1 port 2, ...).  The guest then did offset calculations on the
sqp_base qp number that the PPF passed to it in QUERY_FUNC_CAP().

This is now changed so that the guest does no offset calculations
regarding proxy or tunnel QPs to use.  This change frees the PPF from
needing to adhere to a specific order in allocating proxy and tunnel
QPs.

Now QUERY_FUNC_CAP provides each port individually with its proxy
qp0, proxy qp1, tunnel qp0, and tunnel qp1 QP numbers, and these are
used directly where required (with no offset calculations).

To accomplish this change, several fields were added to the phys_caps
structure for use by the PPF and by non-SR-IOV mode:

    base_sqpn -- in non-sriov mode, this was formerly sqp_start.
    base_proxy_sqpn -- the first physical proxy qp number -- used by PPF
    base_tunnel_sqpn -- the first physical tunnel qp number -- used by PPF.

The current code in the PPF still adheres to the previous layout of
sqps, proxy-sqps and tunnel-sqps.  However, the PPF can change this
layout without affecting VF or (paravirtualized) PF code.

026149cbaa mlx4: Activate SR-IOV mode for IB
Remove the error returns for IB ports from mlx4_ib_add,
mlx4_INIT_PORT_wrapper, and mlx4_CLOSE_PORT_wrapper.

Currently, SRIOV is supported only for devices for which the
link layer is IB on all ports; RoCE support will be added later.

992e8e6e87 IB/mlx4: Miscellaneous adjustments for SR-IOV IB support
1. Allow only master to change node description.
2. Prevent AH leakage in send mads.
3. Take device part number from PCI structure, so that guests see the
   VF part number (and not the PF part number).
4. Place the device revision ID into caps structure at startup.
5. SET_PORT in update_gids_task needs to go through wrapper on master.
6. In mlx4_ib_event(), PORT_MGMT_EVENT needs be handled in a work
   queue on the master, since it propagates events to slaves using
   GEN_EQE.
7. Do not support FMR on slaves.
8. Add spinlock to slave_event(), since it is called both in interrupt
   context and in process context (due to 6 above, and also if
   smp_snoop is used).  This fix was found and implemented by Saeed
   Mahameed <saeedm@mellanox.com>

980e90010f mlx4_core: INIT/CLOSE port logic for IB ports in SR-IOV mode
Normally, INIT_PORT and CLOSE_PORT are invoked when special QP0
transitions to RTR, or transitions to ERR/RESET respectively.

In SR-IOV mode, however, the master is also paravirtualized.  This in
turn requires that we not do INIT_PORT until the entire QP0 path (real
QP0 and proxy QP0) is ready to receive.  When the real QP0 goes down,
we should indicate that the port is not active.

2a4fae148c IB/mlx4: Propagate P_Key and guid change port management events to slaves
P_Key change and guid change events are not of interest to all slaves,
but only to those slaves which "see" the table slots whose contents
have change.

For example, if the guid at port 1, index 5 has changed in the PPF, we
wish to propagate the gid-change event only to the function which has
that guid index mapped to its port/guid table (in this case it is
slave #5). Other functions should not get the event, since the event
does not affect them.

Similarly with P_Keys -- P_Key change events are forwarded only to
slaves which have that P_Key index mapped to their virtual P_Key table.

a0c64a17ab mlx4: Add alias_guid mechanism
For IB ports, we paravirtualize the GUID at index 0 on slaves.  The
GUID at index 0 seen by a slave is the actual GUID occupying the GUID
table at the slave-id index.

The driver, by default, requests at startup time that subnet manager
populate its entire guid table with GUIDs. These guids are then mapped
(paravirtualized) to the slaves, and appear for each slave as its GUID
at index 0.

Until each slave has such a guid, its port status is DOWN.

The guid table is cached to support special QP paravirtualization, and
event propagation to slaves on guid change (we test to see if the guid
really changed before propagating an event to the slave).

To support this caching, add capability to __mlx4_ib_query_gid() to
obtain the network view (i.e., physical view) gid at index X, not just
the host (paravirtualized) view.

993c401e20 mlx4_core: Add IB port-state machine and port mgmt event propagation
For an IB port, a slave should not show port active until that slave
has a valid alias-guid (provided by the subnet manager).  Therefore
the port-up event should be passed to a slave only after both the port
is up, and the slave's alias-guid has been set.

Also, provide the infrastructure for propagating port-management
events (client-reregister, etc) to slaves.

0a9a01884d mlx4: MAD_IFC paravirtualization
The MAD_IFC firmware command fulfills two functions.

First, it is used in the QP0/QP1 MAD-handling flow to obtain
information from the FW (for answering queries), and for setting
variables in the HCA (MAD SET packets).

For this, MAD_IFC should provide the FW (physical) view of the data.
This is the view that OpenSM needs.  We call this the "network view".

In the second case, MAD_IFC is used by various verbs to obtain data
regarding the local HCA (e.g., ib_query_device()).  We call this the
"host view".

This data needs to be paravirtualized.

MAD_IFC therefore needs a wrapper function, and also needs another
flag indicating whether it should provide the network view (when it is
called by ib_process_mad in special-qp packet handling), or the host
view (when it is called while implementing a verb).

There are currently 2 flag parameters in mlx4_MAD_IFC already:
ignore_bkey and ignore_mkey.  These two parameters are replaced by a
single "mad_ifc_flags" parameter, with different bits set for each
flag.  A third flag is added: "network-view/host-view".
