The devlink_snapshot_id_get() function returns a snapshot id. The
snapshot id is a u32, so there is no way to indicate an error code.
A future change is going to possibly add additional cases where this
function could fail. Refactor the function to return the snapshot id in
an argument, so that it can return zero or an error value.
This ensures that snapshot ids cannot be confused with error values, and
aids in the future refactor of snapshot id allocation management.
Because there is no current way to release previously used snapshot ids,
add a simple check ensuring that an error is reported in case the
snapshot_id would over flow.

A future change is going to implement a new devlink command to request
a snapshot on demand. As part of this, the logic for handling the
snapshot ids will be refactored. To simplify the snapshot id allocation
function, move it to a separate function prefixed by `__`. This helper
function will assume the lock is held.
While no other callers will exist, it simplifies refactoring the logic
because there is no need to complicate the function with gotos to handle
unlocking on failure.

A future change is going to add a new devlink command to request
a snapshot on demand. This function will want to call the
devlink_region_snapshot_create function while already holding the
devlink instance lock.
Extract the logic of this function into a static function prefixed by
`__` to indicate that it is an internal helper function. Modify the
original function to be implemented in terms of the new locked

It does not makes sense that two snapshots for a given region would use
different destructors. Simplify snapshot creation by adding
a .destructor op for regions.
This operation will replace the data_destructor for the snapshot
creation, and makes snapshot creation easier.

Modify the devlink region code in preparation for adding new operations
on regions.
Create a devlink_region_ops structure, and move the name pointer from
within the devlink_region structure into the ops structure (similar to
the devlink_health_reporter_ops).
This prepares the regions to enable support of additional operations in
the future such as requesting snapshots, or accessing the region
directly without a snapshot.
In order to re-use the constant strings in the mlx4 driver their
declaration must be changed to 'const char * const' to ensure the
compiler realizes that both the data and the pointer cannot change.

====================
Implement stats_update callback for pedit and skbedit
The stats_update callback is used for adding HW counters to the SW ones.
Both skbedit and pedit actions are actually recognized by flow_offload.h,
but do not implement these callbacks. As a consequence, the reported values
are only the SW ones, even where there is a HW counter available.
Patch #1 adds the callback to action skbedit, patch #2 adds it to action
pedit. Patch #3 tweaks an skbedit selftest with a check that would have
caught this problem.
The pedit test is not likewise tweaked, because the iproute2 pedit action
currently does not support JSON dumping. This will be addressed later.

mlxsw: Offload TC action pedit munge dsfield
Petr says:
The Spectrum switches allow packet prioritization based on DSCP on ingress,
and update of DSCP on egress. This is configured through the DCB APP rules.
For some use cases, assigning a custom DSCP value based on an ACL match is
a better tool. To that end, offload FLOW_ACTION_MANGLE to permit changing
of dsfield as a whole, or DSCP and ECN values in isolation.
After fixing a commentary nit in patch #1, and mlxsw naming in patch #2,
patches #3 and #4 add the offload to mlxsw.
Patch #5 adds a forwarding selftest for pedit dsfield, applicable to SW as
well as HW datapaths. Patch #6 adds a mlxsw-specific test to verify DSCP
rewrite due to DCB APP rules is not performed on pedited packets.
The tests only cover IPv4 dsfield setting. We have tests for IPv6 as well,
but would like to postpone their contribution until the corresponding
iproute patches have been accepted.

("tipc: improve throughput between nodes in netns"), we're missing a check
to handle TIPC_DIRECT_MSG type, it's still using old sending mechanism for
this message type. So, throughput improvement is not significant as
expected.
Besides that, when sending a large message with that type, we're also
handle wrong receiving queue, it should be enqueued in socket receiving
instead of multicast messages.
Fix this by adding the missing case for TIPC_DIRECT_MSG.

Currently eswitch mode change is occurring from 2 different execution
contexts as below.
1. sriov sysfs enable/disable
2. devlink eswitch set commands
Both of them need to access eswitch related data structures in
synchronized manner.
Without any synchronization below race condition exist.
SR-IOV enable/disable with devlink eswitch mode change:
cpu-0 cpu-1
----- -----
mlx5_device_disable_sriov() mlx5_devlink_eswitch_mode_set()
mlx5_eswitch_disable() esw_offloads_stop()
esw_offloads_disable() mlx5_eswitch_disable()
esw_offloads_disable()
Hence, they are synchronized using a new mode_lock.
eswitch's state_lock is not used as it can lead to a deadlock scenario
below and state_lock is only for vport and fdb exclusive access.
ip link set vf <param>
netlink rcv_msg() - Lock A
rtnl_lock
vfinfo()
esw->state_lock() - Lock B
devlink eswitch_set
devlink_mutex
esw->state_lock() - Lock B
attach_netdev()
register_netdev()
rtnl_lock - Lock A
Alternatives considered:
1. Acquiring rtnl lock before taking esw->state_lock to follow similar
locking sequence as ip link flow during eswitch mode set.
rtnl lock is not good idea for two reasons.
(a) Holding rtnl lock for several hundred device commands is not good
idea.
(b) It leads to below and more similar deadlocks.
devlink eswitch_set
devlink_mutex
rtnl_lock - Lock A
esw->state_lock() - Lock B
eswitch_disable()
reload()
ib_register_device()
ib_cache_setup_one()
rtnl_lock()
2. Exporting devlink lock may lead to undesired use of it in vendor
driver(s) in future.
3. Unloading representors outside of the mode_lock requires
serialization with other process trying to enable the eswitch.
4. Differing the representors life cycle to a different workqueue
requires synchronization with func_change_handler workqueue.

devlink_nl_cmd_eswitch_set_doit() doesn't hold devlink->lock mutex while
invoking driver callback. This is likely due to eswitch mode setting
involves adding/remove devlink ports, health reporters or
other devlink objects for a devlink device.
So it is driver responsiblity to ensure thread safe eswitch state
transition happening via either sriov legacy enablement or via devlink
eswitch set callback.
Therefore, get() callback should also be invoked without holding
devlink->lock mutex.
Vendor driver can use same internal lock which it uses during eswitch
mode set() callback.
This makes get() and set() implimentation symmetric in devlink core and
in vendor drivers.
Hence, remove holding devlink->lock mutex during eswitch get() callback.
Failing to do so results into below deadlock scenario when mlx5_core
driver is improved to handle eswitch mode set critical section invoked
by devlink and sriov sysfs interface in subsequent patch.
devlink_nl_cmd_eswitch_set_doit()
mlx5_eswitch_mode_set()
mutex_lock(esw->mode_lock) <- Lock A
[...]
register_devlink_port()
mutex_lock(&devlink->lock); <- lock B
mutex_lock(&devlink->lock); <- lock B
devlink_nl_cmd_eswitch_get_doit()
mlx5_eswitch_mode_get()
mutex_lock(esw->mode_lock) <- Lock A
In subsequent patch, mlx5_core driver uses its internal lock during
get() and set() eswitch callbacks.
Other drivers have been inspected which returns either constant during
get operations or reads the value from already allocated structure.
Hence it is safe to remove the lock in get( ) callback and let vendor
driver handle it.

Group version is used when modifying a rule is allowed
(FLOW_ACT_NO_APPEND is clear) to detect a case where the rule was found
but while the groups where unlocked a new FTE was added. In this case,
the added FTE could be one with identical match value so we need to
attempt again with group lock held.
Change the code so version is retrieved only when FLOW_ACT_NO_APPEND is
cleared. As result, later compare can also be avoided if FLOW_ACT_NO_APPEND
is cleared.

Pull GPIO fixes from Linus Walleij:
- One core quirk by myself to fix the .irq_disable() semantics when the
gpiolib core takes over this callback.
- The rest is an elaborate series of four patches fixing Intel laptop
ACPI wakeup quirks.
* tag 'gpio-v5.6-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpiolib: acpi: Add quirk to ignore EC wakeups on HP x2 10 CHT + AXP288 model

====================
wireless-drivers fixes for v5.6
Fourth, and last, set of fixes for v5.6. Just two important fixes to
iwlwifi regressions.
iwlwifi
* fix GEO_TX_POWER_LIMIT command on certain devices which caused
firmware to crash during initialisation
* add back device ids for three devices which were accidentally
removed

net/netfilter/nft_fwd_netdev.c: In function ‘nft_fwd_netdev_eval’:
net/netfilter/nft_fwd_netdev.c:32:10: error: ‘struct sk_buff’ has no member named ‘tc_redirected’
pkt->skb->tc_redirected = 1;
^~
net/netfilter/nft_fwd_netdev.c:33:10: error: ‘struct sk_buff’ has no member named ‘tc_from_ingress’
pkt->skb->tc_from_ingress = 1;
^~
To avoid a direct dependency with tc actions from netfilter, wrap the
redirect bits around CONFIG_NET_REDIRECT and move helpers to
include/linux/skbuff.h. Turn on this toggle from the ifb driver, the
only existing client of these bits in the tree.
This patch adds skb_set_redirected() that sets on the redirected bit
on the skbuff, it specifies if the packet was redirect from ingress
and resets the timestamp (timestamp reset was originally missing in the
netfilter bugfix).
Fixes: bcfabee1afd99484 ("netfilter: nft_fwd_netdev: allow to redirect to ifb via ingress")

This commit adds support to catch any bits set in SGE_INT_CAUSE5 for Parity Errors.
F_ERR_T_RXCRC flag is used to ignore that particular bit as it is not considered as fatal.
So, we clear out the bit before looking for error.
This patch now read and report separately all three registers(Cause1, Cause2, Cause5).
Also, checks for errors if any.

Since set_rx_mode takes a mutex lock for sending mailbox
message to admin function to set the mode, moved logic
to a workqueue.
