Currently, netdevsim implements dummy FIB offload and marks notified
routes with RTM_F_TRAP flag. netdevsim does not defer route notifications
to a work queue because it does not need to program any hardware.

Given that netdevsim's purpose is to both give an example implementation
and allow developers to test their code, align netdevsim to a "real"
hardware device driver like mlxsw and have it also perform the route
"programming" in a non-atomic context.

It will be used to test route flags notifications which will be added in
the next patches.

The following changes are needed when route handling is performed in WQ:
- Handle the accounting in the main context, to be able to return an
  error for adding route when all the routes are used.
  For FIB_EVENT_ENTRY_REPLACE increase the counter before scheduling
  the delayed work, and in case that this event replaces an existing route,
  decrease the counter as part of the delayed work.

- For IPv6, cannot use fen6_info->rt->fib6_siblings list because it
  might be changed during handling the delayed work.
  Save an array with the nexthops as part of fib6_event struct, and take
  a reference for each nexthop to prevent them from being freed while
  event is queued.

- Change GFP_ATOMIC allocations to GFP_KERNEL.

- Use single work item that is handling a list of ordered routes.
  Handling routes must be processed in the order they were submitted to
  avoid logical errors that could lead to unexpected failures.

When route is added/deleted, the appropriate counter is increased/decreased
to maintain number of routes.

User can limit the number of routes and then according to the appropriate
counter, adding more routes than the limitation is forbidden.

Currently, there is one lock which protects hashtable, list and accounting.

Handling the counters will be performed from both atomic context and
non-atomic context, while the hashtable and the list will be used only from
non-atomic context and therefore will be protected by a separate lock.

Protect accounting by using an atomic variable, so lock is not needed.

====================
net: ipa: don't disable NAPI in suspend

This is version 2 of a series that reworks the order in which things
happen during channel stop and suspend (and start and resume), in
order to address a hang that has been observed during suspend.
The introductory message on the first version of the series gave
some history which is omitted here.

The end result of this series is that we only enable NAPI and the
I/O completion interrupt on a channel when we start the channel for
the first time.  And we only disable them when stopping the channel
"for good."  In other words, NAPI and the completion interrupt
remain enabled while a channel is stopped for suspend.

One comment on version 1 of the series suggested *not* returning
early on success in a function, instead having both success and
error paths return from the same point at the end of the function
block.  This has been addressed in this version.

In addition, this version consolidates things a little bit, but the
net result of the series is exactly the same as version 1 (with the
exception of the return fix mentioned above).

First, patch 6 in the first version was a small step to make patch 7
easier to understand.  The two have been combined now.

Second, previous version moved (and for suspend/resume, eliminated)
I/O completion interrupt and NAPI disable/enable control in separate
steps (patches).  Now both are moved around together in patch 5 and
6, which eliminates the need for the final (NAPI-only) patch.

I won't repeat the patch summaries provided in v1:

Transactions to send data for a network device can be allocated at
any time up until the point the TX queue is stopped.  It is possible
for ipa_start_xmit() to be called in one context just before a
the transmit queue is stopped in another.

Update gsi_channel_trans_last() so that for TX channels the
allocated and pending transaction lists are checked--in addition
to the completed and polled lists--to determine the "last"
transaction.  This means any transaction that has been allocated
before the TX queue is stopped will be allowed to complete before
we conclude the channel is quiesced.

Rework the function a bit to use a list pointer and gotos.

No completion interrupts will occur while an endpoint is suspended,
nor when a channel has been stopped for suspend.  So there's no need
to disable the interrupt during suspend and re-enable it when
resuming.  Without any interrupts occurring, there is no need to
disable/re-enable NAPI for channel suspend/resume either.

We'll only enable NAPI and the interrupt when we first start the
channel, and disable it again only when it's "really" stopped.

To accomplish this, move the enable/disable calls out of
__gsi_channel_start() and __gsi_channel_stop(), and into
gsi_channel_start() and gsi_channel_stop() instead.

Add a call to napi_synchronize() to gsi_channel_suspend(), to ensure
NAPI polling is done before moving on.

Disable both the I/O completion interrupt and NAPI polling on a
channel *after* we successfully stop it rather than before.  This
ensures a completion occurring just before the channel is stopped
gets processed.

Enable NAPI polling and the interrupt *before* starting a channel
rather than after, to be symmetric.  A stopped channel won't
generate any completion interrupts anyway.

Enable NAPI before the interrupt and disable it afterward.

Create a new function that does most of the work of starting a
channel.  What's different is that it takes a flag indicating
whether the channel should really be started or not.  Create
another new function __gsi_channel_stop() that behaves similarly.

IPA v3.5.1 implements suspend using a special SUSPEND endpoint
setting.  If the endpoint is suspended when an I/O completes on the
underlying GSI channel, a SUSPEND interrupt is generated.

Newer versions of IPA do not implement the SUSPEND endpoint mode.
Instead, endpoint suspend is implemented by simply stopping the
underlying GSI channel.  In this case, a completing I/O on a
*stopped* channel causes the SUSPEND interrupt condition.

These new functions put all activity related to starting or stopping
a channel (including "thawing/freezing" the channel) in one place,
whether or not the channel is actually started or stopped.

Avoid the assumption that ksize(kmalloc(S)) == ksize(kmalloc(S)): when
cloning an skb, save and restore truesize after pskb_expand_head(). This
can occur if the allocator decides to service an allocation of the same
size differently (e.g. use a different size class, or pass the
allocation on to KFENCE).

Because truesize is used for bookkeeping (such as sk_wmem_queued), a
modified truesize of a cloned skb may result in corrupt bookkeeping and
relevant warnings (such as in sk_stream_kill_queues()).

With version 0 of the protocol it was legal to encode the 'Subflow Id' in
the MP_PRIO suboption, to specify which subflow would change its 'Backup'
flag. This has been removed from v1 specification: thus, according to RFC
8684 §3.3.8, the resulting 'Length' for MP_PRIO changed from 4 to 3 byte.

Current Linux generates / parses MP_PRIO according to the old spec, using
'Length' equal to 4, and hardcoding 1 as 'Subflow Id'; RFC compliance can
improve if we change 'Length' in other to become 3, leaving a 'Nop' after
the MP_PRIO suboption. In this way the kernel will emit and accept *only*
MP_PRIO suboptions that are compliant to version 1 of the MPTCP protocol.

So far phy_disconnect() is called before free_irq(). If CONFIG_DEBUG_SHIRQ
is set and interrupt is shared, then free_irq() creates an "artificial"
interrupt by calling the interrupt handler. The "link change" flag is set
in the interrupt status register, causing phylib to eventually call
phy_suspend(). Because the net_device is detached from the PHY already,
the PHY driver can't recognize that WoL is configured and powers down the
