In dwmac4_wrback_get_rx_timestamp_status we looking for a RX timestamp.
For that receive descriptors are handled and so we should use defines
related to receive descriptors. It'll no change the functional behavior

====================
Support Mellanox BlueField SmartNIC (mlx5-updates-2019-02-15)
Bodong Wang says,
BlueField device is a multi-core ARM processor in a highly integrated
system on chip coupled with the ConnectX interconnect controller.
BlueField device can be presented in one out of two modes:
- SEPARATED_HOST: ARM processors as a separated and orthogonal host
like any other external host in the multi-host virtualization model.
- EMBEDDED_CPU: ARM processors as Embedded CPU (EC) and part of the
external hosts virtualization model.
While existing driver already supports the device on separated_host
mode, this patch series focus on the functionalities of embedded_cpu
mode.
On embedded_cpu mode, BlueField device exposes regular network
controller PCI function in the BlueField host(e.g, x86). However, a
separate PCI function called Embedded CPU Physical Function(ECPF) is
also added to the ARM host side, where standard Linux distributions is
able to run on the ARM cores. Depends on the NV configuration from
firmware, ECPF can be the e-switch manager and firmware pages supplier.
If ECPF is configured as e-switch manager and page supplier, it will
take over the responsibilities from the PF on BlueField host includes:
- Owns, controls and manages all e-switch parts, and takes e-switch
traffic by default. It also should perform ENABLE_HCA for the host
PF just like a PF does for its VFs.
- Provides and manages the ICM host memory required for the HCA to
store various contexts for itself, the PF and VFs belong the
e-switch it manages.
The PF on BlueField host side is still responsible for:
- Control its own permanent MAC.
- PCI and SRIOV configurations and perform ENABLE_HCA for its VFs.
The ECPF can also retrieve information about the external host it
controls, like host identifier, PCI BDF and number of virtual functions.
As these parameters may be changed dynamically, an event will be triggered
to the driver on ECPF side.

We were not consistent in how the default VID of a given port was
defined, b53_br_leave() would make sure the VLAN ID would be either 0/1
depending on the switch generation, but b53_configure_vlan(), which is
the default configuration would unconditionally set it to 1. The correct
value is 1 for 5325/5365 series and 0 otherwise. To avoid repeating that

Rather than special-casing OSN in a number of places, just give this
device type its own netdev_ops structure.
When setting up the OSN net_device, also skip the handling of the
various HW offloads (eg TSO). The device shouldn't be advertising any of
them, and the OSN code paths in qeth don't have support for them.
In particular RX VLAN filtering is not supported, so don't hook up those
callbacks in the netdev_ops.

Currently, the e-switch driver requires going to legacy mode before
changing to the offloads mode. This makes sense for regular case as
the legacy mode is done by creating VFs.
However, it's problematic when ECPF is the eswitch manager. In such
case, ECPF will control the vports on peer host including the peer
PF and VFs. But ECPF doesn't need and shall not create VFs as the
VFs are created in the peer PF host.
Grant ECPF the ability to change from none to the offloads mode. Note
that currently the only way to go back to none mode is by unloading
the ECPF driver.

When host PF changes the number of VFs, the ECPF esw driver will get
a FW event. It should query the number of VFs enabled by host PF and
update the VF reps accordingly. Note that host PF can't change the
number of VFs dynamically, it has to reset the number of VFs to 0
before changing to a new positive number.
The host event is registered when driver is moving to switchdev mode,
and it's the last step to do in esw_offloads_init. It's unregistered
and the work queue is flushed when driver quits from switchdev mode.
In this way, the host event and devlink command are serialized.
When driver is enabling switchdev mode, pay attention to the following
two facts:
1. Host PF must not have VF initialized as the flow table in ECPF has
ENCAP enabled as default. Such flow table can't be created with
existing initialized VFs.
2. ECPF doesn't know how many VFs the host PF will enable, ECPF
offloads flow steering shall create the flow table/groups based on
the max number of VFs possibly supported by host PF.

ECPF connects to the eswitch through vport 0xfffe. ECPF may or may
not be the eswitch manager depending on firmware configuration.
1. If ECPF is eswitch manager: ECPF will take over the eswitch manager
responsibility. A rep of the host PF shall be created at the ECPF
side for the eswitch manager to control.
2. If ECPF is not eswitch manager: host PF will be the eswitch manager,
ECPF acts similar as a VF to the host PF. Host PF will be aware
of the ECPF vport presence and control it's rep.

In offloads mode, the current implementation puts the uplink
representor at index zero of the vport reps array. It is not "natural"
to place it at index 0 since we want to put the representor for vport
0 at index 0 with the introduction of SmartNIC. A separate patch will
handle the case whether a rep is needed for vport 0 (PF vport).
So, we want to have a different placeholder for uplink vport and
representor. It was placed at the end of vport and rep array. Since
vport number can no longer act as an index into the vport or
representors arrays, use functions to map vport numbers to indices
when accessing the vports or representors arrays, and vice versa.

Eswitch has two users: IB and ETH. They both register repersentors
when mlx5 interface is added, and unregister the repersentors when
mlx5 interface is removed. Ideally, each driver should only deal with
the entities which are unique to itself. However, current IB and ETH
drivers have to perform the following eswitch operations:
1. When registering, specify how many vports to register. This number
is the same for both drivers which is the total available vport
numbers.
2. When unregistering, specify the number of registered vports to do
unregister. Also, unload the repersentors which are already loaded.
It's unnecessary for eswitch driver to hands out the control of above
operations to individual driver users, as they're not unique to each
driver. Instead, such operations should be centralized to eswitch
driver. This consolidates eswitch control flow, and simplified IB and
ETH driver.
This patch doesn't change any functionality.

Currently the driver loads and unloads all reps in an unbreakable
group. However, with ECPF, the reps of special vports such as uplink
and host PF should always be loaded in switchdev mode where the reps
for VFs will be loaded on-demand and unloaded on no-demand. This is
a pre-step for that change.

Currently the eswitch vport reps have a valid indicator, which is
set on register and unset on unregister. However, a rep can be loaded
or not loaded when doing unregister, current driver checks if the
vport of that rep is enabled as a flag to imply the rep is loaded.
However, for ECPF, this is not valid as the host PF will enable the
vports for its VFs instead.
Add three states: {unregistered, registered, loaded}, with the
following state changes across different operations:
create: (none) -> unregistered
reg: unregistered -> registered
load: registered -> loaded
unload: loaded -> registered
unreg: registered -> unregistered
Note that the state shall only be updated inside eswitch driver rather
than individual drivers such as ETH or IB.

With only PF and VF, it is sufficient to have the vport/rep array
index as the vport number. This is because PF and VF vports numbers
are consecutive serial numbers. In downstream patches with
introducing of ECPF and UPLINK vports, it's not consecutive any more.
Use getter to get specific vport/rep, and use iterator to traversal
a list of vport/rep. This hides the translation between array index
and vport number, and provides flexibility of using different
translation mechanism in the future.

When driver is entering offloads mode, there are two major tasks to
do: initialize flow steering and create representors. Flow steering
should make sure enough flow table/group spaces are reserved for all
reps. Representors will be created in a group, all or none.
With the introduction of ECPF, flow steering should still reserve the
same spaces. But, the representors are not always loaded/unloaded in a
single piece. Once ECPF is in offloads mode, it will get the number
of VF changing event from host PF. In such scenario, only the VF reps
should be loaded/unloaded, not the reps for special vports (such as
the uplink vport).
Thus, when entering offloads mode, driver should specify the total
number of reps, and the number of VF reps separately. When leaving
offloads mode, the cleanup should use the information self-contained
in eswitch such as number of VFs.

Commands referring to vports use the following scheme:
1. When referring to my own vport, put 0 in vport and 0 in other_vport.
2. When referring to another vport, put the vport number of the
referred vport and put 1 in other_vport. It was assumed that driver
is accessing other vport when vport number is greater than 0.
With the above scheme, the case that ECPF eswitch manager is trying
to access host PF vport will fall over with scheme 1 as the vport
number is 0. This is apparently wrong as driver is trying to refer
other vport.
As such usage can only happen in the eswitch context, change relevant
functions to provide other vport input properly.

However, the cls_tcindex.c stuff was a bit more complex.

What I've decided to do, in order to resolve this, is revert the

to pure RCU. I did it this way because I believe that either Cong's
races don't apply with have Vlad did things, or Cong will have to

On module unload/remove, we need to ensure that work does not run
after we have freed resources. Concretely, cancel_delayed_work()
may return while the callback function is still running.
From kernel/workqueue.c:
The work callback function may still be running on return,
unless it returns true and the work doesn't re-arm itself.
Explicitly flush or use cancel_delayed_work_sync() to wait on it.

Pull networking fixes from David Miller:
1) Fix MAC address setting in mac80211 pmsr code, from Johannes Berg.
2) Probe SFP modules after being attached, from Russell King.
3) Byte ordering bug in SMC rx_curs_confirmed code, from Ursula Braun.
4) Revert some r8169 changes that are causing regressions, from Heiner
Kallweit.
5) Fix spurious connection timeouts in netfilter nat code, from Florian
Westphal.
6) SKB leak in tipc, from Hoang Le.
7) Short packet checkum issue in mlx4, similar to a previous mlx5
change, from Saeed Mahameed. The issue is that whilst padding bytes
are usually zero, it is not guarateed and the hardware doesn't take
the padding bytes into consideration when generating the checksum.
8) Fix various races in cls_tcindex, from Cong Wang.
9) Need to set stream ext to NULL before freeing in SCTP code, from Xin
Long.
10) Fix locking in phy_is_started, from Heiner Kallweit.

Commit c9b47cc1fabc ("xsk: fix bug when trying to use both copy and
zero-copy on one queue id") moved the umem query code to the AF_XDP
core, and therefore removed the need to query the netdevice for a
umem.
This patch removes XDP_QUERY_XSK_UMEM and all code that implement that
behavior, which is just dead code.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
SoC fixes for omaps for v5.0-rc cycle
This series contains two SoC regression fixes and one uninitialized
variable fix:
- Fix inverted nirq pin handling for omap5 that started producing
warnings with earlier GIC direction checks and took a while to
understand and confirm. Basically there are two sys_nirq pins
that are bypassing peripheral modules and inverted automatically
by the SoC and need to be handled with a custom irq_set_type()
- Recent ti-sysc changes caused a regression to the pwm-omap-dmtimer
code where the device tree handling code for timer source clock
gets confused. It looks like we can remove that code eventually,
but for now we just drop a bogus pm_runtime_irq_safe() for the
timers with the related quirks caused by pm_runtime_irq_safe(),
and have the standard assigned-clocks and assigned-clock-parents
deal with setting the source clock
- Fix potentially uninitialized value for display init code if
regmap_read() fails

The driver's interrupt handler checks whether a message is currently
being handled with the curr_msg pointer. When it is NULL, the interrupt
is considered to be unexpected. Similarly, the i2c_start_transfer
routine checks for the remaining number of messages to handle in
num_msgs.
However, these values are never cleared and always keep the message and
number relevant to the latest transfer (which might be done already and
the underlying message memory might have been freed).
When an unexpected interrupt hits with the DONE bit set, the isr will
then try to access the flags field of the curr_msg structure, leading
to a fatal page fault.
The msg_buf and msg_buf_remaining fields are also never cleared at the
end of the transfer, which can lead to similar pitfalls.
Fix these issues by introducing a cleanup function and always calling
it after a transfer is finished.
