Provide an unlocked version of sfp_sm_event() which can be used by
sfp_check_state() to avoid having to keep re-taking the lock if
several signals have changed state.

Swap the order of the rtnl and st_mutex locks - st_mutex is now nested
beneath rtnl lock instead of rtnl being beneath st_mutex. This will
allow us to hold st_mutex only while manipulating the module's hardware
or software control state.

As preparation to moving st_mutex inside rtnl_lock, we need to first

There are a couple of locations in the code where we modify
sfp->state, and then call sfp_set_state(, sfp->state) to update
the outputs/soft state to control the module. Provide a helper
which takes a mask and new state so that this is encapsulated in
one location.

Florian Westphal says:
====================
Netfilter updates for net-next
nftables updates:
1. Allow key existence checks with maps.
At the moment the kernel requires userspace to pass a destination
register for the associated value, make this optional so userspace
can query if the key exists, just like with normal sets.
2. nftables maintains a counter per set that holds the number of
elements. This counter gets decremented on element removal,
but its only incremented if the set has a upper maximum value.
Increment unconditionally, this will allow us to update the
maximum value later on.
3. At DCCP option maching, from Jeremy Sowden.
4. use struct_size macro, from Christophe JAILLET.
Conntrack:
5. Squash holes in struct nf_conntrack_expect, also Christophe JAILLET.
6. Allow clash resolution for GRE Protocol to avoid a packet drop,
from Faicker Mo.

net: lan966x: Add support for PCP, DEI, DSCP
This patch series extends lan966x to offload to the hardware the
following features:
- PCP: this configuration is per port both at ingress and egress.
- App trust: which allows to specify a trust order of app selectors.
This can be PCP or DSCP or DSCP/PCP.
- default priority
- DSCP: this configuration is shared between the ports both at ingress
and egress.

Add support for DSCP rewrite in lan966x driver. On egress DSCP is
rewritten from either classified DSCP, or frame DSCP. Classified DSCP is
determined by the Analyzer Classifier on ingress, and is mapped from
classified QoS class and DP level. Classification of DSCP is by default
enabled for all ports.
It is required that DSCP is trusted for the egress port *and* rewrite
table is not empty, in order to rewrite DSCP based on classified DSCP,
otherwise DSCP is always rewritten from frame DSCP.

Its currently not allowed to perform queries on a map, for example:
table t {
map m {
typeof ip saddr : meta mark
..
chain c {
ip saddr @m counter
will fail, because kernel requires that userspace provides a destination
register when the referenced set is a map.
However, internally there is no real distinction between sets and maps,
maps are just sets where each key is associated with a value.
Relax this so that maps can be used just like sets.
This allows to have rules that query if a given key exists
without making use of the associated value.
This also permits != checks which don't work for map lookups.
When no destination reg is given for a map, then permit this for named
maps.
Data and dump paths need to be updated to consider priv->dreg_set
instead of the 'set-is-a-map' check.
Checks in reduce and validate callbacks are not changed, this
can be relaxed later if a need arises.

This reverts commit 0920ccdf41e3078a4dd2567eb905ea154bc826e6.
The commit 0920ccdf41e3 ("ARM: dts: stm32: add CAN support on
stm32f746") depends on the patch "dt-bindings: mfd: stm32f7: add
binding definition for CAN3" [1], which is not in net/main, yet. This
results in a parsing error of "stm32f746.dtsi".
So revert this commit.

This function is only used when CONFIG_TRACE_BRANCH_PROFILING is set and
DISABLE_BRANCH_PROFILING is not set, and the declaration is hidden
behind this combination of tests.
But that causes a warning when building with CONFIG_TRACING_BRANCHES,
since that sets DISABLE_BRANCH_PROFILING for the tracing code, and the
declaration is thus hidden:
kernel/trace/trace_branch.c:205:6: error: no previous prototype for 'ftrace_likely_update' [-Werror=missing-prototypes]
Move the declaration out of the #ifdef to avoid the warning.

When running large numbers of pppoe connections, a bucket size of 16 may
be too small and 256 may be more appropriate. This sacrifices some RAM
but should result in faster processing of incoming PPPoE frames.
On our systems we run upwards of 150 PPPoE connections at any point in
time, and we suspect we're starting to see the effects of this small
number of buckets.
The legal values according to pppoe.c is anything that when 8 is divided
by that results in a modulo of 0, ie, 1, 2, 4 and 8.
The size of the per-underlying-interface structure is:
sizeof(rwlock_t) + sizeof(pppox_sock*) * PPPOE_HASH_SIZE.
Assuming a 64-bit pointer this will result in just over a 2KiB structure
for PPPOE_HASH_BITS=8, which will likely result in a 4KiB allocation,
which for us at least is acceptable.
Not sure what the minimum allocation size is, and thus if values of 1
and 2 truly make sense. Default results in historic sizing and
behaviour.

The XPCS expects clause 73 (copper backplane) autoneg to follow the
ethtool autoneg bit. It actually did that until the blamed
commit inaptly replaced state->an_enabled (coming from ethtool) with
phylink_autoneg_inband() (coming from the device tree or struct
phylink_config), as part of an unrelated phylink_pcs API conversion.
Russell King suggests that state->an_enabled from the original code was
just a proxy for the ethtool Autoneg bit, and that the correct way of
restoring the functionality is to check for this bit in the advertising
mask.

In suspend and resume cycle, the removal and rescan of device ends
up in NULL pointer dereference.
During driver initialization, if the ipc_imem_wwan_channel_init()
fails to get the valid device capabilities it returns an error and
further no resource (wwan struct) will be allocated. Now in this
situation if driver removal procedure is initiated it would result
in NULL pointer exception since unallocated wwan struct is dereferenced
inside ipc_wwan_deinit().
ipc_imem_run_state_worker() to handle the called functions return value
and to release the resource in failure case. It also reports the link
down event in failure cases. The user space application can handle this
event to do a device reset for restoring the device communication.
