c753119e6d fjes: Add debugfs entry for EP status information in fjes driver
This patch adds debugfs entry to show EP status information.
You can get each EP's status information like the following:

  # cat /sys/kernel/debug/fjes/fjes.0/status

EPID    STATUS           SAME_ZONE        CONNECTED
ep0     shared           Y                Y
ep1     -                -                -
ep2     unshared         N                N
ep3     unshared         N                N
ep4     unshared         N                N
ep5     unshared         N                N

d5df7688b6 qed: Fix possible race when reading firmware return code.
While handling SPQ ramrod completion, there is a possible race
where driver might not read updated fw return code based on
ramrod completion done. This patch ensures that fw return code
is written first and then completion done flag is updated
using appropriate memory barriers.

7eff82b0fc qed: Handle malicious VFs events
Malicious VFs might be caught in several different methods:
  - Misusing their bar permission and being blocked by hardware.
  - Misusing their fastpath logic and being blocked by firmware.
  - Misusing their interaction with their PF via hw-channel,
    and being blocked by PF driver.

On the first two items, firmware would indicate to driver that
the VF is to be considered malicious, but would sometime still
allow the VF to communicate with the PF [depending on the exact
nature of the malicious activity done by the VF].
The current existing logic on the PF side lacks handling of such events,
and might allow the PF to perform some incorrect configuration on behalf
of a VF that was previously indicated as malicious.

The new scheme is simple -
Once the PF determines a VF is malicious it would:
 a. Ignore any further requests on behalf of the VF-driver.
 b. Prevent any configurations initiated by the hyperuser for
    the malicious VF, as firmware isn't willing to serve such.

The malicious indication would be cleared upon the VF flr,
after which it would become usable once again.

c59f5291fd qed: Allow chance for fast ramrod completions
Whenever a ramrod is being sent for some device configuration,
the driver is going to sleep at least 5ms between each iteration
of polling on the completion of the ramrod.

However, in almost every configuration scenario the firmware
would be able to comply and complete the ramrod in a manner of
several usecs. This is especially important in cases where there
might be a lot of sequential configurations applying to the hardware
[e.g., RoCE], in which case the existing scheme might cause some
visible user delays.

This patch changes the completion scheme - instead of immediately
starting to sleep for a 'long' period, allow the device to quickly
poll on the first iteration after a couple of usecs.

7b7e70f979 qed*: Allow unicast filtering
Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not
actually performing unicast MAC filtering.
While we're at it - relax a hard-coded limitation that limits each
interface into using at most 15 unicast MAC addresses before turning
promiscuous. Instead utilize the HW resources to their limit.

to detect properties of a given 'tc_action'.

'is_tcf_mirred_redirect' tests that the action is TCA_EGRESS_REDIR.
'is_tcf_mirred_mirror' tests that the action is TCA_EGRESS_MIRROR.

As a prep towards supporting INGRESS redir/mirror, rename these
predicates to reflect their true meaning:

3c293f4e08 net: phy: Trigger state machine on state change and not polling.
The phy_start() is used to indicate the PHY is now ready to do its
work. The state is changed, normally to PHY_UP which means that both
the MAC and the PHY are ready.

If the phy driver is using polling, when the next poll happens, the
state machine notices the PHY is now in PHY_UP, and kicks off
auto-negotiation, if needed.

If however, the PHY is using interrupts, there is no polling. The phy
is stuck in PHY_UP until the next interrupt comes along. And there is
no reason for the PHY to interrupt.

Have phy_start() schedule the state machine to run, which both speeds
up the polling use case, and makes the interrupt use case actually
work.

This problems exists whenever there is a state change which will not
cause an interrupt. Trigger the state machine in these cases,
e.g. phy_error().

all protocols can be handled. Rearrange code to eliminate goto

This is a temporary solution; recent versions of Window Server etc

d1ef006dc1 xen-netback: fix guest Rx stall detection (after guest Rx refactor)
If a VIF has been ready for rx_stall_timeout (60s by default) and an
Rx ring is drained of all requests an Rx stall will be incorrectly
detected.  When this occurs and the guest Rx queue is empty, the Rx
ring's event index will not be set and the frontend will not raise an
event when new requests are placed on the ring, permanently stalling
the VIF.

This is a regression introduced by eb1723a29b (xen-netback:
refactor guest rx).

Fix this by reinstating the setting of queue->last_rx_time when
placing a packet onto the guest Rx ring.

Problem is that this is doing a BUILD_BUG_ON on a non-constant
expression because of trying to take offset of pas[i] in the
structure.

Fix is to create MLX5_ARRAY_SET64 that takes an additional argument
that is the field index to separate between BUILD_BUG_ON on the array
constant field and the indexed field to assign the value to.
There are two callers of MLX5_SET64 that are trying to get a variable
offset, change those to call MLX5_ARRAY_SET64 passing 'pas' and 'i'
as the arguments to use in the offset check and the indexed value
assignment.

is that the "set DTR" functionality depends on chipset and/or
baseband firmware generation. But USB3 is still an optional feature.

Since we cannot enable this unconditionally for all older devices, and
there doesn't appear to be anything we can use in the USB descriptors
to identify these chips, we are forced to use a device specific quirk
flag.

1e09c106a4 tlan: avoid unused label with PCI=n
While build testing with randconfig on x86, I ran into this warning
that appears to have been around forever

drivers/net/ethernet/ti/tlan.c: In function ‘tlan_probe1’:
drivers/net/ethernet/ti/tlan.c:614:1: error: label ‘err_out’ defined but not used [-Werror=unused-label]

This can be trivially avoided by just moving the label into the
existing #ifdef.

a9339b8e13 xen-netback: (re-)create a debugfs node for hash information
It is useful to be able to see the hash configuration when running tests.
This patch adds a debugfs node for that purpose.

The original version of this patch (commit c0c64c1523) was reverted due
to build failures caused by a conflict with commit 0364a8824c
("xen-netback: switch to threaded irq for control ring"). This new version
of the patch is nearly identical to the original, the only difference
being that creation of the debugfs node is predicated on 'ctrl_irq' being
non-zero rather then the now non-existent 'ctrl_task'.

a52ad514fd net: deprecate eth_change_mtu, remove usage
With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.

Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

This commit removes explicit includes except the following:

  * tools/testing/radix-tree/linux/kernel.h

These two are used for host programs.

3989144f86 kthread: kthread worker API cleanup
A good practice is to prefix the names of functions by the name
of the subsystem.

The kthread worker API is a mix of classic kthreads and workqueues.  Each
worker has a dedicated kthread.  It runs a generic function that process
queued works.  It is implemented as part of the kthread subsystem.

This patch renames the existing kthread worker API to use
the corresponding name from the workqueues API prefixed by
kthread_:

__init_kthread_worker()		-> __kthread_init_worker()
init_kthread_worker()		-> kthread_init_worker()
init_kthread_work()		-> kthread_init_work()
insert_kthread_work()		-> kthread_insert_work()
queue_kthread_work()		-> kthread_queue_work()
flush_kthread_work()		-> kthread_flush_work()
flush_kthread_worker()		-> kthread_flush_worker()

Note that the names of DEFINE_KTHREAD_WORK*() macros stay
as they are. It is common that the "DEFINE_" prefix has
precedence over the subsystem names.

Note that INIT() macros and init() functions use different
naming scheme. There is no good solution. There are several
reasons for this solution:

  + "init" in the function names stands for the verb "initialize"
    aka "initialize worker". While "INIT" in the macro names
    stands for the noun "INITIALIZER" aka "worker initializer".

  + INIT() macros are used only in DEFINE() macros

  + init() functions are used close to the other kthread()
    functions. It looks much better if all the functions
    use the same scheme.

  + There will be also kthread_destroy_worker() that will
    be used close to kthread_cancel_work(). It is related
    to the init() function. Again it looks better if all
    functions use the same naming scheme.

  + there are several precedents for such init() function
    names, e.g. amd_iommu_init_device(), free_area_init_node(),
    jump_label_init_type(),  regmap_init_mmio_clk(),

  + It is not an argument but it was inconsistent even before.
