There are several error handling bugs in mscc_ocelot_init_ports(). I
went through the code, and carefully audited it and made fixes and
cleanups.
1) The ocelot_probe_port() function didn't have a mirror release function
so it was hard to follow. I created the ocelot_release_port()
function.
2) In the ocelot_probe_port() function, if the register_netdev() call
failed, then it lead to a double free_netdev(dev) bug. Fix this by
setting "ocelot->ports[port] = NULL" on the error path.
3) I was concerned that the "port" which comes from of_property_read_u32()
might be out of bounds so I added a check for that.
4) In the original code if ocelot_regmap_init() failed then the driver
tried to continue but I think that should be a fatal error.
5) If ocelot_probe_port() failed then the most recent devlink was leaked.
The fix for mostly came Vladimir Oltean. Get rid of "registered_ports"
and just set a bit in "devlink_ports_registered" to say when the
devlink port has been registered (and needs to be unregistered on
error). There are fewer than 32 ports so a u32 is large enough for
this purpose.
6) The error handling if the final ocelot_port_devlink_init() failed had
two problems. The "while (port-- >= 0)" loop should have been
"--port" pre-op instead of a post-op to avoid a buffer underflow.
The "if (!registered_ports[port])" condition was reversed leading to
resource leaks and double frees.

This converts the driver to use the new tasklet API introduced in
commit 12cc923f1ccc ("tasklet: Introduce new initialization API")
It is unfortunate that we need to add a pointer to the driver context to
get back to the usbnet device, but the space will be reclaimed once
there are no more users of the old API left and we can remove the data
value and flag from the tasklet struct.

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.

Transactions to send data for a network device can be allocated at

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.

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.

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

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.

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
PHY.

result in crashes.

recalculation natively. Older devices require this additional recalculation.
