The non-zero check on rc is redundant as a previous non-zero
check on rc will always return and the second check is never
reached, hence it is redundant and can be removed. Also
remove a blank line.

When netvsc_attach() is called by operations like changing MTU, etc.,
an extra wakeup may happen while netvsc_attach() calling
rndis_filter_device_add() which sends rndis messages when queue is
stopped in netvsc_detach(). The completion message will wake up queue 0.
We can reproduce the issue by changing MTU etc., then the wake_queue
counter from "ethtool -S" will increase beyond stop_queue counter:
stop_queue: 0
wake_queue: 1
The issue causes queue wake up, and counter increment, no other ill
effects in current code. So we didn't see any network problem for now.
To fix this, initialize tx_disable to true, and set it to false when
the NIC is ready to be attached or registered.

usbnet creates network interfaces with min_mtu = 0 and
max_mtu = ETH_MAX_MTU.
These values are not modified by qmi_wwan when the network interface
is created initially, allowing, for example, to set mtu greater than 1500.
When a raw_ip switch is done (raw_ip set to 'Y', then set to 'N') the mtu
values for the network interface are set through ether_setup, with
min_mtu = ETH_MIN_MTU and max_mtu = ETH_DATA_LEN, not allowing anymore to
set mtu greater than 1500 (error: mtu greater than device maximum).
The patch restores the original min/max mtu values set by usbnet after a
raw_ip switch.

After introducing the router lock in previous patches and making sure it
protects internal router structures, we no longer need to rely on RTNL
to serialize access to these structures.
Remove RTNL from call sites that no longer require it.
Two calls sites that keep taking the lock are
mlxsw_sp_router_fibmr_event_work() and mlxsw_sp_inet6addr_event_work().
The first calls into ACL code that still assumes RTNL is taken. The
second potentially calls into the FID code that also relies on RTNL.
Removing RTNL from these two call sites is the subject of future work.

The dpipe code traverses internal router structures such as neighbours
and adjacency entries and dumps them to user space via netlink. Up until
now the routing code did not have its own locks and relied on RTNL lock
to serialize access. This is going to change with the introduction of

taken so that the latter could be removed by subsequent patches.

Introduce a mutex to protect the internal structure of the routing code.
A single lock is added instead of a more fine-grained and complicated
locking scheme because there is not a lot of concurrency in the routing
code.
The main motivation is remove the dependence on RTNL lock, which is
currently used by both the process pushing routes to the kernel and the
workqueue pushing the routes to the underlying device.

When a host route is added, the driver checks if the route needs to be
promoted to perform NVE decapsulation based on the current NVE
configuration. If so, the index of the decapsulation entry is retrieved
and associated with the route.
Currently, this information is stored in the NVE module which the router
module consults. Since the information is protected under RTNL and since
route insertion happens with RTNL held, there is no problem to retrieve
the information from the NVE module.
However, this is going to change and route insertion will no longer
happen under RTNL. Instead, a dedicated lock will be introduced for the
router module.
Therefore, store this information in the router module and change the
router module to consult this copy.
The validity of the information is set / cleared whenever an NVE tunnel
is initialized / de-initialized. When this happens the NVE module calls
into the router module to promote / demote the relevant host route.

The driver periodically traverses the linked list of multicast routes
and updates the kernel about packets and bytes statistics from each
multicast route. These statistics are read from a counter associated
with the route when it is written to the device.
Currently, multicast routes are published via this linked list before
they are associated with a counter. Despite that, it is not possible for
the driver to access an invalid counter because the delayed work that
reads the statistics and multicast route addition / deletion are
mutually exclusive using RTNL.
In order to be able to remove RTNL, the list needs to be protected by a
dedicated lock, but any route published via the list must have an
associated counter, otherwise the driver will access an invalid counter.
Solve this by re-ordering the operations during multicast route addition
so that the route is only added to the linked list after it was written
to the device. Similarly, during deletion the route is first removed
from the linked list before its deletion from the device.

FW flash status notify is currently implemented via a callback to the
caller mlx module, and all it is doing is to call
devlink_flash_update_status_notify with the specific module devlink
instance.
Instead of repeating the whole process for all mlx modules and
re-implement the status_notify callback again and again. Just provide the
devlink instance as part of mlxfw_dev when calling mlxfw_firmware_flash
and let mlxfw do the devlink status updates directly.
This will be very useful for adding status notify support to mlx5, as
already done in this patch, with a simple one line of just providing the
devlink instance to mlxfw_firmware_flash.
mlxfw now depends on NET_DEVLINK as all other mlx modules.

Set the speed optimization bit on the DP83867 PHY.
This feature can also be strapped on the 64 pin PHY devices
but the 48 pin devices do not have the strap pin available to enable
this feature in the hardware. PHY team suggests to have this bit set.
With this bit set the PHY will auto negotiate and report the link
parameters in the PHYSTS register. This register provides a single
location within the register set for quick access to commonly accessed
information.
In this case when auto negotiation is on the PHY core reads the bits
that have been configured or if auto negotiation is off the PHY core
reads the BMCR register and sets the phydev parameters accordingly.
This Giga bit PHY can throttle the speed to 100Mbps or 10Mbps to accomodate a
4-wire cable. If this should occur the PHYSTS register contains the
current negotiated speed and duplex mode.
In overriding the genphy_read_status the dp83867_read_status will do a
genphy_read_status to setup the LP and pause bits. And then the PHYSTS
register is read and the phydev speed and duplex mode settings are
updated.

Functions starting with __ usually indicate those which are exported,
but should not be called directly. Update some of those declared in the
API and make it more readable.
page_pool_unmap_page() and page_pool_release_page() were doing
exactly the same thing calling __page_pool_clean_page(). Let's
rename __page_pool_clean_page() to page_pool_release_page() and
export it in order to show up on perf logs and get rid of
page_pool_unmap_page().
Finally rename __page_pool_put_page() to page_pool_put_page() since we
can now directly call it from drivers and rename the existing
page_pool_put_page() to page_pool_put_full_page() since they do the same
thing but the latter is trying to sync the full DMA area.
This patch also updates netsec, mvneta and stmmac drivers which use
those functions.

After the previous patch, all the callers of mlxsw_sp_rif_find_by_dev()
outside of the routing code use it to understand if a RIF exists for the
passed netdev.
Therefore, export a function to check if a RIF exists and make
mlxsw_sp_rif_find_by_dev() internal to the routing code.
This will later allow us to more easily introduce the router lock which
will also protect the RIFs.
