Ido Schimmel c1bb279cfa rocker: Create an ordered workqueue for FIB offload
As explained in the previous commits, we need to process FIB entries
addition / deletion events in FIFO order or otherwise we can have a
mismatch between the kernel's FIB table and the device's.

Create an ordered workqueue for rocker to which these work items will be
submitted to.

Ido Schimmel 3057224e01 mlxsw: spectrum_router: Implement FIB offload in deferred work
FIB offload is currently done in process context with RTNL held, but
we're about to dump the FIB tables in RCU critical section, so we can no
longer sleep.

Instead, defer the operation to process context using deferred work. Make
sure fib info isn't freed while the work is queued by taking a reference
on it and releasing it after the operation is done.

Deferring the operation is valid because the upper layers always assume
the operation was successful. If it's not, then the driver-specific
abort mechanism is called and all routed traffic is directed to slow
path.

The work items are submitted to an ordered workqueue to prevent a
mismatch between the kernel's FIB table and the device's.

Ido Schimmel a3832b3189 mlxsw: core: Create an ordered workqueue for FIB offload
We're going to start processing FIB entries addition / deletion events
in deferred work. These work items must be processed in the order they
were submitted or otherwise we can have differences between the kernel's
FIB table and the device's.

Solve this by creating an ordered workqueue to which these work items
will be submitted to. Note that we can't simply convert the current
workqueue to be ordered, as EMADs re-transmissions are also processed in
deferred work.

Later on, we can migrate other work items to this workqueue, such as FDB
notification processing and nexthop resolution, since they all take the
same lock anyway.

David S. Miller db7e9f7c56 Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2016-12-02

This series contains updates to i40e and i40evf only.

Alex provides changes so that we are much more robust about defining what
we can and cannot offload in i40e and i40evf by doing additional checks
other than L4 tunnel header length.

Jake provides several fixes/changes, first cleaning up a label that is
unnecessary, as well as cleaned up the use of a "magic number".  Clarified
the code by separating the global private flags and the regular private
flags per interface into two arrays, so that future additions will not
produce duplication and buggy code.  Adds additional checks to protect
against NULL values for msix_entries and q_vectors pointers.

Michal adds Clause22 method for accessing registers for some external
PHYs.

Piotr adds additional protocol support for the admin queue discover
capabilities function.

Tushar Dave fixes a panic seen on SPARC, where writel() should not be
used to write directly to a memory address but only to a memory mapped
I/O address otherwise it causes data access exceptions.

Joe Perches separates out a section of code into its own function, to
help reduce i40evf_reset_task() a bit.

Alan fixes an issue by checking for NULL before dereferencing msix_entries
and returning early in the case where it is NULL within the i40evf_close()
code path.

Henry provides code cleanup to remove unreachable and redundant sections
of code.  Fixed up an issue where new NICs were not identifying "unknown
PHYs" correctly.

Harshitha fixes a issue where the ethtool "Supported Link" modes list
backplane interfaces on X722 devices for 10 GbE with SFP+ and Cortina
retimer, where these interfaces should not be visible to the user since
they cannot use them.

Carolyn changes an X722 informational message so that it only appears
when extra messages are desired.

Edward Cree e01b16a7e2 sfc: remove EFX_BUG_ON_PARANOID, use EFX_WARN_ON_[ONCE_]PARANOID instead
Logically, EFX_BUG_ON_PARANOID can never be correct.  For, BUG_ON should
 only be used if it is not possible to continue without potential harm;
 and since the non-DEBUG driver will continue regardless (as the BUG_ON is
 compiled out), clearly the BUG_ON cannot be needed in the DEBUG driver.
So, replace every EFX_BUG_ON_PARANOID with either an EFX_WARN_ON_PARANOID
 or the newly defined EFX_WARN_ON_ONCE_PARANOID.

As of commit 8f32b90981

ARM allmodconfig builds would fail modpost with:

ERROR: "cpdma_chan_set_weight" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!

ERROR: "cpdma_chan_set_rate" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!

Since these weren't declared as static, it is assumed they were

was simply overlooked.

As David Miller pointed out for for the previous patch, the whitespace

This fixes the indentation in the file and removes extraneous whitespace
at the end of the lines and before tabs.

David S. Miller 2745529ac7 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Couple conflicts resolved here:

1) In the MACB driver, a bug fix to properly initialize the
   RX tail pointer properly overlapped with some changes
   to support variable sized rings.

2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
   overlapping with a reorganization of the driver to support
   ACPI, OF, as well as PCI variants of the chip.

3) In 'net' we had several probe error path bug fixes to the
   stmmac driver, meanwhile a lot of this code was cleaned up
   and reorganized in 'net-next'.

4) The cls_flower classifier obtained a helper function in
   'net-next' called __fl_delete() and this overlapped with
   Daniel Borkamann's bug fix to use RCU for object destruction
   in 'net'.  It also overlapped with Jiri's change to guard
   the rhashtable_remove_fast() call with a check against
   tc_skip_sw().

5) In mlx4, a revert bug fix in 'net' overlapped with some
   unrelated changes in 'net-next'.

6) In geneve, a stale header pointer after pskb_expand_head()
   bug fix in 'net' overlapped with a large reorganization of
   the same code in 'net-next'.  Since the 'net-next' code no
   longer had the bug in question, there was nothing to do
   other than to simply take the 'net-next' hunks.

Jacob Keller 435c084aad i40e: set broadcast promiscuous mode for each active VLAN
A previous workaround added to ensure receipt of all broadcast frames
incorrectly set the broadcast promiscuous mode unconditionally
regardless of active VLAN status.

Replace this partial workaround with a complete solution that sets the
broadcast promiscuous filters in i40e_sync_vsi_filters. This new method
sets the promiscuous mode based on when broadcast filters are added or
removed.

I40E_VLAN_ANY will request a broadcast filter for all VLANs, (as we're
in untagged mode) while a broadcast filter on a specific VLAN will only
request broadcast for that VLAN.

Thus, we restore addition of broadcast filter to the array, but we add
special handling for these such that they enable the broadcast
promiscuous mode instead of being sent as regular filters.

The end result is that we will correctly receive all broadcast packets
(even those with a *source* address equal to the broadcast address) but
will not receive packets for which we don't have an active VLAN filter.

Tushar Dave 2f7679ee2e i40e: fix panic on SPARC while changing num of desc
On SPARC, writel() should not be used to write directly to memory
address but only to memory mapped I/O address otherwise it causes
data access exception.

Commit 147e81ec75 ("i40e: Test memory before ethtool alloc
succeeds") introduced a code that uses memory address to fake the HW
tail address and attempt to write to that address using writel()
causes kernel panic on SPARC. The issue is reproduced while changing
number of descriptors using ethtool.

This change resolves the panic by using HW read-only memory mapped
I/O register to fake HW tail address instead memory address.

This change makes it so that we are much more robust about defining what we
can and cannot offload.  Previously we were performing no checks.  This
should bring us up to parity with the i40e PF driver.

In addition the device only supports GSO as long as the MSS is 64 or
greater.  We were not checking this so an MSS less than that was resulting
in Tx hangs.

Marcin Wojtas 2636ac3cc2 net: mvneta: Add network support for Armada 3700 SoC
Armada 3700 is a new ARMv8 SoC from Marvell using same network controller
as older Armada 370/38x/XP. There are however some differences that
needed taking into account when adding support for it:

* open default MBUS window to 4GB of DRAM - Armada 3700 SoC's Mbus
  configuration for network controller has to be done on two levels:
  global and per-port. The first one is inherited from the
  bootloader. The latter can be opened in a default way, leaving
  arbitration to the bus controller.  Hence filled mbus_dram_target_info
  structure is not needed

* make per-CPU operation optional - Recent patches adding RSS and XPS
  support for Armada 38x/XP enabled per-CPU operation of the controller
  by default. Contrary to older SoC's Armada 3700 SoC's network
  controller is not capable of per-CPU processing due to interrupt lines'
  connectivity.  This patch restores non-per-CPU operation, which is now
  optional and depends on neta_armada3700 flag value in mvneta_port
  structure. In order not to complicate the code, separate interrupt
  subroutine is implemented.

For now, on the Armada 3700, RSS is disabled as the current
implementation depend on the per cpu interrupts.
